java Apache POI Word现有表插入带有单元格样式和格式的行

Question

我是Apache POI中的一个重要人物,并希望在单词tamplate文件中扩展一些存在的表.如果我使用下面的代码,表格将扩展为行位,新行的单元格创建正常样式.

我的目标是细胞具有相同的表格细胞样式等(字体,有,高...)

    XWPFDocument doc = new XWPFDocument(openFile(fileName));
    XWPFTable tbl = doc.getTableArray(tableIndex);
    XWPFTableRow lastRow = tbl.getRows().get(tbl.getNumberOfRows() - 1);
    cellCounter = lastRow.getTableICells().size(); 
    XWPFTableRow newRow = tbl.createRow(); 
    for (int i = 0; i < data.size() && cellCounter <= data.size(); i++) {         
    String text = data.get(i);
        XWPFTableCell cell = newRow.getCell(i);
        if (cell != null) {
            cell.setText(text);
        }
    }

感谢您的回答.R.

以下代码获取文档中包含的第一个表中第二行的精确副本.然后它会更改此行中单元格的文本内容.然后在此表的第2行和第3行之间插入此复制的行.

不断变化的内容必须之前完成table.addRow,因为该行必须在插入之前完整列表tableRows并将其添加到TrArray了的CTTbl ctTbl.后来的改变不会写入XML.我真的不明白为什么会这样.

然后代码获取最后一行的副本,并在表的末尾添加此副本.这里也必须在改变内容之前完成table.addRow.

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

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

public class WordInsertTableRow {

 public static void main(String[] args) throws Exception {

  XWPFDocument doc = new XWPFDocument(new FileInputStream("source.docx"));

  XWPFTable table = doc.getTableArray(0);

//insert new row, which is a copy of row 2, as new row 3:
  XWPFTableRow oldRow = table.getRow(1);
  CTRow ctrow = CTRow.Factory.parse(oldRow.getCtRow().newInputStream());
  XWPFTableRow newRow = new XWPFTableRow(ctrow, table);

  int i = 1;
  for (XWPFTableCell cell : newRow.getTableCells()) {
   for (XWPFParagraph paragraph : cell.getParagraphs()) {
    for (XWPFRun run : paragraph.getRuns()) {
     run.setText("New row 3 cell " + i++, 0);
    }
   }
  }

  table.addRow(newRow, 2);

//insert new last row, which is a copy previous last row:
  XWPFTableRow lastRow = table.getRows().get(table.getNumberOfRows() - 1);
  ctrow = CTRow.Factory.parse(lastRow.getCtRow().newInputStream());
  newRow = new XWPFTableRow(ctrow, table);

  i = 1;
  for (XWPFTableCell cell : newRow.getTableCells()) {
   for (XWPFParagraph paragraph : cell.getParagraphs()) {
    for (XWPFRun run : paragraph.getRuns()) {
     run.setText("New last row cell " + i++, 0);
    }
   }
  }

  table.addRow(newRow);

  doc.write(new FileOutputStream("result.docx"));
  doc.close();

 }
}
