回复： How to copy a table and modify it correctly in the same docx fileusing POI?

[尘 <44...@qq.com>]

You're right, I thought the codes just replace the content of the new table to be the old one, but actually it turns out  they refer to the same table unless I save and reopen the document. However, I can't just re-creating a new table and fill it because the table I need has a complex style, so copying a existing one seems to be the best way. Finally I made it by construct a table using the template table's "CTTbl" before using setTable() to avoid referring to the same table . Look at the piece of the codes,


	public static void copyTable() throws Exception {
		XWPFDocument doc = new XWPFDocument(new FileInputStream(
				"styledTable.docx"));
		XWPFTable table = doc.getTables().get(0);


                 // Copying a existing table
		 CTTbl ctTbl = CTTbl.Factory.newInstance(); // Create a new CTTbl for the new table
		 ctTbl.set(table.getCTTbl()); // Copy the template table's CTTbl
		 XWPFTable table2 = new XWPFTable(ctTbl, doc); // Create a new table using the CTTbl upon
		 table2.getRow(5).getCell(0).setText("123"); // Modify the new table
		 doc.createParagraph();
		 doc.createTable(); // Create a empty table in the document
		 doc.setTable(1, table2);  // Replace the empty table to table2


                  // Copying a existing table row‍
		 CTRow ctRow = CTRow.Factory.newInstance();
		 XWPFTableRow row = table.getRow(5);
		 ctRow.set(row.getCtRow());
		 XWPFTableRow row2 = new XWPFTableRow(ctRow, table);
		 row2.getCell(0).setText("123");
		 table.addRow(row2);


		FileOutputStream out = new FileOutputStream("styledTable2.docx");
		doc.write(out);
		out.close();
	}‍



By this way I could correctly copy a existing table and modify the two tables independently as well as the table row. Maybe there's a better way to solve this problem, anyway, it does works.

Because they're passed by reference not by content.   You're better off
just re-creating the table as needed than copying an existing one.

Hi, usign apache-poi-3.7 I think I found a shorter way to do it

/CTTbl tbl = template.getDocument().getBody().insertNewTbl(tableIndex);

tbl.set(original.getCTTbl());

XWPFTable table2 = new XWPFTable(tbl, template);

table2.getRows().get(0).getCell(0).setText("test");/

where

*template*: XWPFDocument
*original*: original table to be duplicated
*tableIndex*: no javadoc found, I suppose is the position of the table, if i
put 0, the "position" of the original table, the duplicated one is created
but completely attached to the original
