RegionUtil.setBorderLeft(1, cellRangeAddress, sheet, wb); RegionUtil.setBorderBottom(1, cellRangeAddress, sheet, wb); RegionUtil.setBorderRight(1, cellRangeAddress, sheet, wb); RegionUtil.setBorderTop(1, cellRangeAddress, sheet, wb);
上面是加边框的核心代码,为单元格的上,下左,右四边加边框!我测试在单个合并单元格的时候,是没有什么问题的!但是当我用下面代码的时候会出现有的边框没有
Row row=sheet.createRow((short)0); ImageUtil.createCell("排序", 0, sctext, row); CellRangeAddress CellRangeAddress1 = new CellRangeAddress(0,2,0,0); sheet.addMergedRegion(CellRangeAddress1); RegionUtil.setBorderLeft(1, cellRangeAddress, sheet, wb); RegionUtil.setBorderBottom(1, cellRangeAddress, sheet, wb); RegionUtil.setBorderRight(1, cellRangeAddress, sheet, wb); RegionUtil.setBorderTop(1, cellRangeAddress, sheet, wb); ImageUtil.createCell("项目名称", 1, sctext, row); CellRangeAddress CellRangeAddress2 = new CellRangeAddress(0,2,1,1); sheet.addMergedRegion(CellRangeAddress2); ImageUtil.createCell("姓名", 2, sctext, row); CellRangeAddress CellRangeAddress3 = new CellRangeAddress(0,2,2,2); sheet.addMergedRegion(CellRangeAddress3); ImageUtil.createCell("各指标完成情况总数据", 3, sctext, row); CellRangeAddress CellRangeAddress4 = new CellRangeAddress(0,0,3,8); sheet.addMergedRegion(new CellRangeAddress(0,0,3,8)); ImageUtil.createCell("各指标完成率", 9, sctext, row); CellRangeAddress CellRangeAddress5 = new CellRangeAddress(0,0,9,14); sheet.addMergedRegion(CellRangeAddress5); Row row2=sheet.createRow((short)1); ImageUtil.createCell("覆盖面", 3, sctext, row2); CellRangeAddress CellRangeAddress6 = new CellRangeAddress(1,1,3,4); sheet.addMergedRegion(CellRangeAddress6); ImageUtil.createCell("频次", 5, sctext, row2); CellRangeAddress CellRangeAddress7 = new CellRangeAddress(1,1,5,6); sheet.addMergedRegion(CellRangeAddress7);
结果如下图:
最后在没有办法的情况下,只能一点点调试。结果确十分坑爹,折腾了我好几个小时上网看资料。最后原来是以为顺序问题导致的.
其原因是因为在编辑单元格的时候,后者覆盖了前者的style.
解决办法:
封装了一个方法:
public void setBorder(CellRangeAddress cellRangeAddress, Sheet sheet, Workbook wb) throws Exception { RegionUtil.setBorderLeft(1, cellRangeAddress, sheet, wb); RegionUtil.setBorderBottom(1, cellRangeAddress, sheet, wb); RegionUtil.setBorderRight(1, cellRangeAddress, sheet, wb); RegionUtil.setBorderTop(1, cellRangeAddress, sheet, wb); }然后将调用该方法的步骤放到最后,记得是最后,就是全部单元格合并之后,否则会覆盖的,如下:
super.setBorder(CellRangeAddress1, sheet, book); super.setBorder(CellRangeAddress2, sheet, book); super.setBorder(CellRangeAddress3, sheet, book); super.setBorder(CellRangeAddress4, sheet, book); super.setBorder(CellRangeAddress5, sheet, book); super.setBorder(CellRangeAddress6, sheet, book); super.setBorder(CellRangeAddress7, sheet, book); super.setBorder(CellRangeAddress8, sheet, book); super.setBorder(CellRangeAddress9, sheet, book); super.setBorder(CellRangeAddress10, sheet, book); super.setBorder(CellRangeAddress11, sheet, book); super.setBorder(CellRangeAddress12, sheet, book); super.setBorder(CellRangeAddress13, sheet, book); super.setBorder(CellRangeAddress14, sheet, book); super.setBorder(CellRangeAddress15, sheet, book); super.setBorder(CellRangeAddress16, sheet, book);
