poi修改ppt表格单元格内容不生效

[wenbei1000]

请问各位大神，如题，我在输出文件前，将cell的内容打印出来，结果显示已经修改成功了，但是ppt.write之后，只有文本框内修改成功，表格中未成功。使用XMLSlideShow修改pptx中单元格内容则可成功，这是POI的BUG吗？有解决办法不呢？
关键代码如下：
FileInputStream is = new FileInputStream(inputFilePath);
HSLFSlideShow ppt = new HSLFSlideShow(is);
is.close();

for (HSLFSlide slide : ppt.getSlides()) {
List<List<HSLFTextParagraph>> txts = slide.getTextParagraphs();
Comment[] cos = slide.getComments();
for(Comment co : cos) {
System.out.println(co);
}
for (List<HSLFTextParagraph> txt : txts) {
List<HSLFTextParagraph> paras = txt;
for (HSLFTextParagraph para : paras) {
List<HSLFTextRun> runs = para.getTextRuns();
for (HSLFTextRun run : runs) {
if(run.getRawText() != ""){
String beforeStr = run.getRawText();
String result = beforeStr.replace("1", "*");
run.setText(result);
}
}
}
}

for (HSLFShape sh : slide.getShapes()) {
if(sh instanceof HSLFTable){
HSLFTable table = (HSLFTable)sh;
int columnNum = table.getNumberOfColumns();
int rowNum = table.getNumberOfRows();

for (int i = 0; i < rowNum; i++) {
for (int j = 0; j < columnNum; j++) {
HSLFTableCell cell = table.getCell(i, j);

if (cell != null) { //避免合并单元格造成的空指针异常
String beforeStr = cell.getText();
String result = beforeStr.replace("1", "*");
cell.setText(result).setText(result);

}
}


}

}

}
}

FileOutputStream output=new FileOutputStream(outputFilePath);
ppt.write(output);

楼主好高端，只用C#操作过word，感觉用java操作微软的东西好麻烦。正常来说估计是楼主用错了或api改了，一般不会出现这种Bug。
