  sheet.addMergedRegion(ExcelTool.getCellRangeAddress(0,89,1,89));
  sheet.addMergedRegion(ExcelTool.getCellRangeAddress(0,90,1,90));

 

只有第一个,"基础字段"合并了有效果,其他后面的字段都没合并

Answer 1

简单测试了一下没有问题：
[code="java"]
import java.io.FileOutputStream;
import java.io.IOException;

import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

public class TestMerge {
public void test()throws IOException {
XSSFWorkbook wb=new XSSFWorkbook();
Sheet sheet=wb.createSheet();
dxqdHeadLine(sheet, wb);
wb.write(new FileOutputStream("d:/1.xlsx"));
}

private void dxqdHeadLine(Sheet sheet, XSSFWorkbook wb) {
    Row header = sheet.createRow(0);// 第一行
    // //第一行内容
    createCell(wb, header, 0, "基础字段");
    createCell(wb, header, 27, "回访环节情况");
    createCell(wb, header, 32, "预处理情况");
    createCell(wb, header, 40, "处理环节情况");
    createCell(wb, header, 48, "定性审核环节");
    createCell(wb, header, 56, "定性复核环节");
    createCell(wb, header, 64, "分公司细化定责环节");
    createCell(wb, header, 69, "原始服务产品类型");
    createCell(wb, header, 71, "最终定性结果");
    createCell(wb, header, 82, "客户属性");
    createCell(wb, header, 89, "关联省公司考核班组");
    createCell(wb, header, 90, "关联分公司考核班组");

    sheet.addMergedRegion(ExcelTool.getCellRangeAddress(0, 0, 0, 26));
    sheet.addMergedRegion(ExcelTool.getCellRangeAddress(0, 27, 0, 31));
    sheet.addMergedRegion(ExcelTool.getCellRangeAddress(0, 32, 0, 39));
    sheet.addMergedRegion(ExcelTool.getCellRangeAddress(0, 40, 0, 47));
    sheet.addMergedRegion(ExcelTool.getCellRangeAddress(0, 48, 0, 55));
    sheet.addMergedRegion(ExcelTool.getCellRangeAddress(0, 56, 0, 63));
    sheet.addMergedRegion(ExcelTool.getCellRangeAddress(0, 64, 0, 68));
    sheet.addMergedRegion(ExcelTool.getCellRangeAddress(0, 69, 0, 70));
    sheet.addMergedRegion(ExcelTool.getCellRangeAddress(0, 71, 0, 81));
    sheet.addMergedRegion(ExcelTool.getCellRangeAddress(0, 82, 0, 88));
    sheet.addMergedRegion(ExcelTool.getCellRangeAddress(0, 89, 1, 89));
    sheet.addMergedRegion(ExcelTool.getCellRangeAddress(0, 90, 1, 90));
}

private void createCell(XSSFWorkbook wb, Row header, int column, String text) {
    Cell cell=header.createCell(column);
    cell.setCellValue(text);
}

public static void main(String[] args)throws Exception {
    new TestMerge().test();
}

}[/code]

[code="java"]import org.apache.poi.ss.util.CellRangeAddress;

public class ExcelTool {

public static CellRangeAddress getCellRangeAddress(int firstRow,
        int firstCol, int lastRow, int lastCol) {
    return new CellRangeAddress(firstRow, lastRow, firstCol, lastCol);
}

}[/code]
是不是你把参数的行号、列号搞错了
