又get到一種思路，不光是layui。

layui,動態表頭,代碼

外面這層table，就是用原生拼接的。

@Override  public List<Map<String, Object>> distribution(String begin,String end,String name,String hospitalCode) {    HashMap<String, Object> params = new HashMap<String, Object>();    StringBuffer buf = new StringBuffer();        List<HRateAllotDepartment> hRateAllotDepartment = rateAllotDepartmentDao.getRateDepartment(hospitalCode);    String str1 = "";    String str2 = "";    for(int i=0;i<hRateAllotDepartment.size();i++) {      str1 +=",sum(`"+hRateAllotDepartment.get(i).getDepartmentName()+"`)`"+hRateAllotDepartment.get(i).getDepartmentName()+"`";      str2 +=",max(case when e.`name`='"+hRateAllotDepartment.get(i).getDepartmentName()+"' then f.price else 0 end) `"+hRateAllotDepartment.get(i).getDepartmentName()+"`";        }        buf.append("select d.`name`,d.productId_,count(*) renshu,sum(price) total"+str1+" ");    buf.append(" from ( SELECT b.`name`,b.id productId_ ,d.id,max(b.price) price ");    buf.append(" "+str2+" FROM ");    buf.append(" dt_pay_health_order_product a "        + "JOIN dt_pay_health_order d ON a.orderId = d.id "        + "JOIN dt_pay_health_product b ON a.productId = b.id ");    buf.append(" JOIN dt_hospital_health_item c ON b.bizId = c.id "        + "JOIN dt_hospital_health_order_use g ON g.orderProductId = a.id "        + "JOIN dt_hospital_rate_allot f ON b.id = f.productId ");    buf.append(" JOIN dt_hospital_department e ON f.departmentId = e.id where g.createDate>=:begin and g.createDate<=:end and b.name like :name and a.state ='02' group by b.`id`,d.`id` ) d group by d.productId_ WITH ROLLUP ");    if(begin == null || begin.length() == 0){      begin = "1970-01-01";    }    if(end == null || end.length() == 0){      end = "2099-01-01";    }    params.put("begin",begin);    params.put("end",end);    params.put("name","%"+name+"%");    return this.getMapListByMap(buf.toString(), params);           }

可以看到，一開始是有一個list，這個list是醫院醫生可以配置的科室，這些科室就是動態的。這樣一來后臺即可得到動態數據。同理，如果在layui時用到page，在這里返回成page類型即可。接下來再看js

function toList(begin,end,name){        console.log(begin);    console.log(end);        $.ajax({      url: basePath + "/biz/hospital/rate/allot/list.do",      data: {        begin:begin,        end:end,        name:name      },      type : 'post',      dataType : 'json',      success : function(data) {                  var arrayPrice = new Array();        for(var i=0;i<data.length;i++){          var arrayPrice1 = new Array();        for(var key in data[i]){                    if(key!="name"&&key!="productId_"&&key!="renshu"&&key!="total"){            arrayPrice1[key]=data[i][key];          }          }        arrayPrice.push(arrayPrice1);      }                var        var sumCols="";        var partCols=new Array();                for(var i=0;i<arrayPrice.length;i++){                    var partColsStr = "";                    for(var key in arrayPrice[i]){                    if(i==0&&(arrayPrice[arrayPrice.length-1][key]!=0)){               title+="<th class='firstTh'>"+key+"（元）</th>";            }            if(i==(arrayPrice.length-1)&&(arrayPrice[arrayPrice.length-1][key]!=0)){              sumCols+="<td class='secondTd'>"+arrayPrice[i][key]+"</td>";            }            if(i!=(arrayPrice.length-1)&&(arrayPrice[arrayPrice.length-1][key]!=0)){              partColsStr += "<td class='thirdTd'>"+arrayPrice[i][key]+"</td>";                          }                     }                    partCols.push(partColsStr);                  }        var sRenshu = 0;        var stotal = 0;                var tablex = "";                tablex += "<tr class='firstTr'><th class='firstTh'>項目名稱</th><th class='firstTh'>檢查人數</th><th class='firstTh'>金額（元）</th>"+title+"</tr>";                if(data!=null && data.length>0){          for(var i=0;i<data.length-1;i++){            sRenshu+=data[i].renshu;            stotal+=data[i].total;          }                    tablex += "<tr class='secondTr'><td class='secondTd'>總計</td><td class='secondTd'>"+sRenshu+"</td><td class='secondTd'>"+stotal+"</td>"+sumCols+"</tr>";                    for(var i=0;i<data.length-1;i++){             {              tablex += "<tr class='thirdTr'><td class='thirdTd'>"+data[i].name+"</td>" +                  "<td class='thirdTd'>" +                    "<a style='color:#ff5722' href="+basePath +" rel="external nofollow" rel="external nofollow" /biz/hospital/rate/allot/toPageMx.do?startDate="+$("#startDate").val().toString()                                              +"&endDate="+$("#endDate").val().toString()                                              +"&productId_="+data[i].productId_+">"+                                              data[i].renshu+"</a></td>" +                  "<td class='thirdTd'>"+data[i].total+ partCols[i] +                  "</tr>";            }          }                  }        $("#table_status").empty();        $("#table_status").append(tablex);                  },      error : function() {        layer.msg('系統異常，請聯系管理員!',{icon:2,time:2000});      }    });          }

可以在最上方圖看到，有些字段是固定的，但是有些字段是動態的。思路是通過將調用接口返回出來的數據，動態的部分放到一個鍵值對數組下。這樣一來，固定的部分，依然可以用返回的data得到，而動態的部分，用處理的數組循環賦值即可。動態表頭就是動態數組的鍵。數據就是值。

function toList(begin,end,name){        console.log(begin);    console.log(end);        $.ajax({      url: basePath + "/biz/hospital/rate/allot/list.do",      data: {        begin:begin,        end:end,        name:name      },      type : 'post',      dataType : 'json',      success : function(data) {                  var arrayPrice = new Array();        for(var i=0;i<data.length;i++){          var arrayPrice1 = new Array();        for(var key in data[i]){                    if(key!="name"&&key!="productId_"&&key!="renshu"&&key!="total"){            arrayPrice1[key]=data[i][key];          }          }        arrayPrice.push(arrayPrice1);      }                var        var sumCols="";        var partCols=new Array();                for(var i=0;i<arrayPrice.length;i++){                    var partColsStr = "";                    for(var key in arrayPrice[i]){                    if(i==0&&(arrayPrice[arrayPrice.length-1][key]!=0)){               title+="<th class='firstTh'>"+key+"（元）</th>";            }            if(i==(arrayPrice.length-1)&&(arrayPrice[arrayPrice.length-1][key]!=0)){              sumCols+="<td class='secondTd'>"+arrayPrice[i][key]+"</td>";            }            if(i!=(arrayPrice.length-1)&&(arrayPrice[arrayPrice.length-1][key]!=0)){              partColsStr += "<td class='thirdTd'>"+arrayPrice[i][key]+"</td>";                          }                     }                    partCols.push(partColsStr);                  }        var sRenshu = 0;        var stotal = 0;                var tablex = "";                tablex += "<tr class='firstTr'><th class='firstTh'>項目名稱</th><th class='firstTh'>檢查人數</th><th class='firstTh'>金額（元）</th>"+title+"</tr>";                if(data!=null && data.length>0){          for(var i=0;i<data.length-1;i++){            sRenshu+=data[i].renshu;            stotal+=data[i].total;          }                    tablex += "<tr class='secondTr'><td class='secondTd'>總計</td><td class='secondTd'>"+sRenshu+"</td><td class='secondTd'>"+stotal+"</td>"+sumCols+"</tr>";                    for(var i=0;i<data.length-1;i++){             {              tablex += "<tr class='thirdTr'><td class='thirdTd'>"+data[i].name+"</td>" +                  "<td class='thirdTd'>" +                    "<a style='color:#ff5722' href="+basePath +" rel="external nofollow" rel="external nofollow" /biz/hospital/rate/allot/toPageMx.do?startDate="+$("#startDate").val().toString()                                              +"&endDate="+$("#endDate").val().toString()                                              +"&productId_="+data[i].productId_+">"+                                              data[i].renshu+"</a></td>" +                  "<td class='thirdTd'>"+data[i].total+ partCols[i] +                  "</tr>";            }          }                  }        $("#table_status").empty();        $("#table_status").append(tablex);                  },      error : function() {        layer.msg('系統異常，請聯系管理員!',{icon:2,time:2000});      }    });          }

這塊是name這些的是固定的，就排除掉，然后將數據放到arrayPrice1下再push到數組下。tablex就是表格的html。當時拼接的是分兩步，先是表頭，然后是數據。有個總計，后來在sql下加了WITH ROLLUP就得到了。

for(var key in arrayPrice[i]){            if(i==0&&(arrayPrice[arrayPrice.length-1][key]!=0)){           title+="<th class='firstTh'>"+key+"（元）</th>";        }        if(i==(arrayPrice.length-1)&&(arrayPrice[arrayPrice.length-1][key]!=0)){          sumCols+="<td class='secondTd'>"+arrayPrice[i][key]+"</td>";        }        if(i!=(arrayPrice.length-1)&&(arrayPrice[arrayPrice.length-1][key]!=0)){          partColsStr += "<td class='thirdTd'>"+arrayPrice[i][key]+"</td>";                  }             }

這塊就是動態的數據，title表頭，sumCols總計，partColsStr具體數據，加到tablex下就行。以上就是原生的思路。

layui,動態表頭,代碼

這塊table用到了layui，當時也是看著這個layui動態設置的思路去寫的原生。主要思路是：cols是一個數組，通過ajax得到數據后放到數組下，再放到cols下即可。

$.ajax({  url: basePath + "/biz/hospital/rate/allot/department/getDepartment.do",  data: {    },  type : 'post',  dataType : 'json',  success : function(data) {    mycols[0] = {field : 'nameTrue', title:"姓名", align:'center',width:'120'};    mycols[1] = {field : 'telephoneTrue', title:'支付手機號', align:'center',width:'120'};    mycols[2] = {field : 'orderNO', title:'訂單號', align:'center',width:'120'};    mycols[3] = {field : 'createDate', title:'訂單創建時間', align:'center',width:'120'};    mycols[4] = {field : 'modifyDate', title:'訂單使用時間', align:'center',width:'120'};    mycols[5] = {field : 'price', title:'支付金額（元）', align:'center',width:'120'};        for (var i = 0;i < data.length; i++){       var obj = data[i].departmentName;      if(obj!=0){        mycols[i+6] = {field : obj, title:obj+"（元）", align:'center',width:'120'};      }            }      console.log(mycols);    reload();    },  error : function() {    layer.msg('系統異常，請聯系管理員!',{icon:2,time:2000});  }});

以上是ajax調用后處理的數組。下面這些就是table。reload();就是重新渲染。

var options = {      url: basePath + "/biz/hospital/rate/allot/list_mx.do",      method: 'post',      where:{        begin:$("#startDate").val().toString(),        end:end,        productId_:$("#productId_").val().toString(),        orderNO:$("#qorderNO").val().toString(),        name:$("#qname").val().toString()      },      //分頁請求參數      request:{        pageName: 'pageIndex', //頁碼        limitName: 'limit' //每頁多少數據      },      //返回的數據格式      response:{         statusName: 'status', //數據狀態的字段名稱，默認：code         statusCode: 200, //成功的狀態碼，默認：0         msgName: 'message', //狀態信息的字段名稱，默認：msg         countName: 'total', //數據總數的字段名稱，默認：count         dataName: 'data' //數據列表的字段名稱，默認：data      },      //每頁10條數據      limit: 10,            //加載時出現加載條      loading: true,      elem: '#data_table',      cols: [        mycols       ],                    id: 'dataTable',      page: true,      };    //方法級渲染  table.render(options);function reload(){        date = new Date($("#endDate").val());        date=date.setDate(date.getDate()+1);    date=new Date(date);      datemonth=date.getMonth()+1;   //獲取當前月份(0-11,0代表1月)    end=date.getFullYear()+"-"+datemonth+"-"+date.getDate();        //options.where.departmentId = $("#departmentId").val();    options.where.begin = $("#startDate").val();    options.where.end = end;    options.where.orderNO = $("#qorderNO").val();;    options.where.name = $("#qname").val();;         table.reload("dataTable",options);      }

可以看到
