我正在尝试在 XWPFDocument 和合并单元格的帮助下创建以下标题。

下图显示了我正在尝试创建的标题的图像

在此处输入图像描述

*XWPFDocument document = new XWPFDocument();
XWPFTable table = document.createTable(1, 8);*
CTTblBorders borders = table.getCTTbl().getTblPr().addNewTblBorders();
borders.addNewBottom().setVal(STBorder.THICK);
borders.addNewLeft().setVal(STBorder.NONE);
borders.addNewRight().setVal(STBorder.NONE);
borders.addNewTop().setVal(STBorder.THICK);
borders.addNewInsideV().setVal(STBorder.THICK);
table.getCTTbl().getTblPr().setTblBorders(borders);
table.setWidth(1440);

for (int col = 0 ; col < 8; col++) {
CTTblWidth tblWidth = table.getRow(0).getCell(col).getCTTc().addNewTcPr().addNewTcW();
tblWidth.setW(BigInteger.valueOf(1440));
//STTblWidth.DXA is used to specify width in twentieths of a point.
tblWidth.setType(STTblWidth.DXA);
}    
**mergeCellHorizontally(table, 0, 0, 1);**
XWPFTableCell cell = table.getRow(0).getCell(1);
CTTcPr ctTcPr = cell.getCTTc().getTcPr();
CTTcBorders ctTcBorders = ctTcPr.addNewTcBorders();
ctTcBorders.addNewRight().setVal(STBorder.NONE);
ctTcBorders.addNewBottom().setVal(STBorder.NONE);

此类表格问题的第一个问题始终是：表格最多有多少列？或者换句话说：有多少列计算表中列最多的行？如果该答案已知，则应创建具有该最大列数的表。通过设置列宽、单元格边框和/或合并单元格，所有其他的都是可能的。

但是在您的特殊情况下，我看不出合并单元格有什么帮助。假设最大列数为 8，则应该可以通过设置列宽和单元格边框来创建示例表。

例子：

import java.io.File;
import java.io.FileOutputStream;

import java.math.BigInteger;

import org.apache.poi.xwpf.usermodel.*;

import org.openxmlformats.schemas.wordprocessingml.x2006.main.*;

public class CreateWordTableSpecial {

 static void setColumnWidth(XWPFTable table, int row, int col, int width) {
  CTTblWidth tblWidth = CTTblWidth.Factory.newInstance();
  tblWidth.setW(BigInteger.valueOf(width));
  tblWidth.setType(STTblWidth.DXA);
  CTTcPr tcPr = table.getRow(row).getCell(col).getCTTc().getTcPr();
  if (tcPr != null) {
   tcPr.setTcW(tblWidth);
  } else {
   tcPr = CTTcPr.Factory.newInstance();
   tcPr.setTcW(tblWidth);
   table.getRow(row).getCell(col).getCTTc().setTcPr(tcPr);
  }
 }

 static void setCellBorders(XWPFTableCell cell, STBorder.Enum[] borderTypesLTRB) {
  CTTcBorders borders = CTTcBorders.Factory.newInstance();
  borders.addNewLeft().setVal(borderTypesLTRB[0]);
  borders.addNewTop().setVal(borderTypesLTRB[1]);
  borders.addNewRight().setVal(borderTypesLTRB[2]);
  borders.addNewBottom().setVal(borderTypesLTRB[3]);
  CTTcPr tcPr = cell.getCTTc().getTcPr();
  if (tcPr != null) {
   tcPr.setTcBorders(borders);
  } else {
