您好，我正在尝试将一个表从一个docx文件复制到另一个docx文件，但实际情况是，该表的值在新文档中的表下方和表外部被复制（请参见下面的图片）
Talbe在新的docx里
正如您所见，表的值被复制到表的外部。我使用的是Libre Office，ApachePOI版本3.17，我的电脑运行的是Ubuntu 16.04
我用来执行复制的代码如下
public static void copyTable(XWPFDocument input_doc,XWPFDocument output_doc,
int table_index_input, int table_index_output) {
XWPFTable template_table = input_doc.getTables().get(table_index_input);
CTTbl ctTbl = CTTbl.Factory.newInstance(); // Create a new CTTbl for the new table
ctTbl.set(template_table.getCTTbl()); // Copy the template table's CTTbl
XWPFTable new_table = new XWPFTable(ctTbl, output_doc); // Create a new table using the CTTbl upon
output_doc.createParagraph();
output_doc.createTable();// Create a empty table in the document
output_doc.setTable(table_index_output, new_table); // Replace the empty table to table2
}
XWPFTable newTbl = output_doc.insertNewTbl(cursor);
copyTable(table, newTbl);
以及copyTable（）方法
private void copyTable(XWPFTable source, XWPFTable target) {
target.getCTTbl().setTblPr(source.getCTTbl().getTblPr());
target.getCTTbl().setTblGrid(source.getCTTbl().getTblGrid());
for (int r = 0; r<source.getRows().size(); r++) {
XWPFTableRow targetRow = target.createRow();
XWPFTableRow row = source.getRows().get(r);
targetRow.getCtRow().setTrPr(row.getCtRow().getTrPr());
for (int c=0; c<row.getTableCells().size(); c++) {
//newly created row has 1 cell
XWPFTableCell targetCell = c==0 ? targetRow.getTableCells().get(0) : targetRow.createCell();
XWPFTableCell cell = row.getTableCells().get(c);
targetCell.getCTTc().setTcPr(cell.getCTTc().getTcPr());
XmlCursor cursor = targetCell.getParagraphArray(0).getCTP().newCursor();
for (int p = 0; p < cell.getBodyElements().size(); p++) {
IBodyElement elem = cell.getBodyElements().get(p);
if (elem instanceof XWPFParagraph) {
XWPFParagraph targetPar = targetCell.insertNewParagraph(cursor);
cursor.toNextToken();
XWPFParagraph par = (XWPFParagraph) elem;
copyParagraph(par, targetPar);
} else if (elem instanceof XWPFTable) {
XWPFTable targetTable = targetCell.insertNewTbl(cursor);
XWPFTable table = (XWPFTable) elem;
copyTable(table, targetTable);
cursor.toNextToken();
}
}
//newly created cell has one default paragraph we need to remove
targetCell.removeParagraph(targetCell.getParagraphs().size()-1);
}
}
//newly created table has one row by default. we need to remove the default row.
target.removeRow(0);
}
第（）段
private void copyParagraph(XWPFParagraph source, XWPFParagraph target) {
target.getCTP().setPPr(source.getCTP().getPPr());
for (int i=0; i<source.getRuns().size(); i++ ) {
XWPFRun run = source.getRuns().get(i);
XWPFRun targetRun = target.createRun();
//copy formatting
targetRun.getCTR().setRPr(run.getCTR().getRPr());
//no images just copy text
targetRun.setText(run.getText(0));
}
}
我认为更简单、更可靠的copyTable函数形式应该是这样的。
private void copyTable(XWPFTable source, XWPFTable target) {
CTTbl sourceCTTbl = source.getCTTbl();
CTTbl targetCTTbl = target.getCTTbl();
targetCTTbl.setTblPr(sourceCTTbl.getTblPr());
targetCTTbl.setTrArray(sourceCTTbl.getTrArray());
}
（至少对我有用）
