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.

POI?
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.
