我使用POI-3.14并且XWPFRun的setText()方法似乎不起作用。我已经尝试了 setText（java.lang.String value）和 setText（java.lang.String value，int pos）。新文本根本没有出现在表格中。
我只需要在表格的第一列设置文字。
以下是代码：
XWPFDocument doc = new XWPFDocument(OPCPackage.open(document));
List<XWPFTable> table = doc.getTables();
//Output stream
FileOutputStream out = new FileOutputStream(file);
for (XWPFTable xwpfTable : table) {
List<XWPFTableRow> row = xwpfTable.getRows();
for (XWPFTableRow xwpfTableRow : row) {
XWPFTableCell cell = xwpfTableRow.getTableCells().get(0);
for (XWPFParagraph p : cell.getParagraphs()) {
for (XWPFRun r : p.getRuns()) {
r.setText("new", 0);
}
}
}
}
doc.write(out);
out.close();
UPD：当我将FileOutputStream添加到同一个文件时，然后调用doc.write（out）我会遇到多个异常。然后原始文件变空。
例外：

为FileOutputStream创建临时文件会得到相同的结果。只有现在原始文件和临时文件都是空的。
