POI中可能會(huì)用到一些需要設(shè)置Excel單元格格式的操作小結(jié)：

先獲取工作薄對(duì)象:

HSSFWorkbook wb = new HSSFWorkbook();

HSSFSheet sheet = wb.createSheet();

HSSFCellStyle setBorder = wb.createCellStyle();

一、設(shè)置背景色：

setBorder.setFillForegroundColor((short) 13);// 設(shè)置背景色

setBorder.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);

二、設(shè)置邊框:

setBorder.setBorderBottom(HSSFCellStyle.BORDER_THIN); //下邊框

setBorder.setBorderLeft(HSSFCellStyle.BORDER_THIN);//左邊框

setBorder.setBorderTop(HSSFCellStyle.BORDER_THIN);//上邊框

setBorder.setBorderRight(HSSFCellStyle.BORDER_THIN);//右邊框

三、設(shè)置居中:

setBorder.setAlignment(HSSFCellStyle.ALIGN_CENTER); // 居中

四、設(shè)置字體:

HSSFFont font = wb.createFont();

font.setFontName("黑體");

font.setFontHeightInPoints((short) 16);//設(shè)置字體大小

HSSFFont font2 = wb.createFont();

font2.setFontName("仿宋_GB2312");

font2.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD);//粗體顯示

font2.setFontHeightInPoints((short) 12);

setBorder.setFont(font);//選擇需要用到的字體格式

五、設(shè)置列寬:

sheet.setColumnWidth(0, 3766); //第一個(gè)參數(shù)代表列id(從0開始),第2個(gè)參數(shù)代表寬度值

六、設(shè)置自動(dòng)換行:

setBorder.setWrapText(true);//設(shè)置自動(dòng)換行

七、合并單元格:

Region region1 = new Region(0, (short) 0, 0, (short) 6);

//參數(shù)1：行號(hào) 參數(shù)2：起始列號(hào) 參數(shù)3：行號(hào) 參數(shù)4：終止列號(hào)

sheet.addMergedRegion(region1);
