为此，创建一个文本运行，并在这些文本运行中插入字段"PAGE \\\\* MERGEFORMAT"和/或"NUMPAGES \\\\* MERGEFORMAT" 。 这也是Word的GUI所做的。

...

run = paragraph.createRun();

run.setText("Page ");

paragraph.getCTP().addNewFldSimple().setInstr("PAGE \\* MERGEFORMAT");

run = paragraph.createRun();

run.setText(" of ");

paragraph.getCTP().addNewFldSimple().setInstr("NUMPAGES \\* MERGEFORMAT");

...

具有这些字段的文本运行当然也可以在表格单元格中。
