Question

使用poi操作word时如何在有多个表格的word中定位到其中一个表格

Answer 1

关键代码如下：
FileInputStream fileInputStream = new FileInputStream( soureFile);
POIFSFileSystem pfs = new POIFSFileSystem( fileInputStream );
HWPFDocument hwpf = new HWPFDocument(pfs);// make a HWPFDocument object

OutputStream output = new FileOutputStream( targetFile );
hwpf.write(output);// write to the target file
output.close();

（2）再word中插入表格。HWPF的情况：
Table tcDataTable = range.insertTableBefore( (short)column , row);//column and row列数和行数
tcDataTable.getRow(i).getCell(j).getParagraph(0).getCharacterRun(0).insertBefore("插入i行j列的内容" );

XWPF的情况：
String outputFile = "D:\\test.doc";

XWPFDocument document = new XWPFDocument();

XWPFTable tableOne = document.createTable();

XWPFTableRow tableOneRowOne = tableOne.getRow(0);
tableOneRowOne.getCell(0).setText("11");
XWPFTableCell cell12 = tableOneRowOne.createCell();
cell12.setText("12");
// tableOneRowOne.addNewTableCell().setText("第1行第2列");
// tableOneRowOne.addNewTableCell().setText("第1行第3列");
// tableOneRowOne.addNewTableCell().setText("第1行第4列");

XWPFTableRow tableOneRowTwo = tableOne.createRow();
tableOneRowTwo.getCell(0).setText("21");
tableOneRowTwo.getCell(1).setText("22");
// tableOneRowTwo.getCell(2).setText("第2行第3列");

XWPFTableRow tableOneRow3 = tableOne.createRow();
tableOneRow3.addNewTableCell().setText("31");
tableOneRow3.addNewTableCell().setText("32");

FileOutputStream fOut;

try {
fOut = new FileOutputStream(outputFile);

document.write(fOut);
fOut.flush();
// 操作结束，关闭文件
fOut.close();
} catch (Exception e) {
e.printStackTrace();
}
