table 中的页码

Page number in a table

我创建了一种在 Word 文档页脚中添加一行三列的 table 的方法。现在,我正在尝试将页码添加到中间栏,但我发现的只是将页码直接添加到页脚上。我已经使用了该代码,但我无法做到。 有人可以帮忙吗?

这是适用于 table

的代码
static public void footer(XWPFDocument doc) {

    CTSectPr sectPr = doc.getDocument().getBody().addNewSectPr();
    XWPFHeaderFooterPolicy footerPolicy= new XWPFHeaderFooterPolicy(doc, sectPr);

    XWPFFooter footer = footerPolicy.createFooter(XWPFHeaderFooterPolicy.DEFAULT);

    XWPFRun run;

    // create table in footer
    XWPFParagraph pgh1 = footer.createParagraph();
    XmlCursor cursor = pgh1.getCTP().newCursor();
    XWPFTable table = footer.insertNewTbl(cursor);
    XWPFTableRow row = table.getRow(0);
    if (row == null) row = table.createRow();
    int twipsPerInch = 1440;
    table.getCTTbl().addNewTblGrid().addNewGridCol().setW(BigInteger.valueOf(7 * twipsPerInch));

    XWPFTableCell cell = row.getCell(0);
    if (cell == null) cell = row.createCell();
    CTTblWidth tblWidth = cell.getCTTc().addNewTcPr().addNewTcW();
    tblWidth.setW(BigInteger.valueOf(2 * twipsPerInch));
    tblWidth.setType(STTblWidth.DXA);
    pgh1 = cell.getParagraphs().get(0);
    run = pgh1.createRun();
    run.setText("blah blah blah");

    cell = row.getCell(1);
    if (cell == null) cell = row.createCell();
    tblWidth = cell.getCTTc().addNewTcPr().addNewTcW();
    tblWidth.setW(BigInteger.valueOf(3 * twipsPerInch));
    tblWidth.setType(STTblWidth.DXA);
    XWPFParagraph pageNumberParagraph = cell.getParagraphs().get(0); 
    pageNumberParagraph.setAlignment(ParagraphAlignment.CENTER);
    run = pageNumberParagraph.createRun();
    run.setText("1");

    cell = row.getCell(2);
    if (cell == null) cell = row.createCell();
    tblWidth = cell.getCTTc().addNewTcPr().addNewTcW();
    tblWidth.setW(BigInteger.valueOf(2 * twipsPerInch));
    tblWidth.setType(STTblWidth.DXA);
    pgh1 = cell.getParagraphs().get(0);
    pgh1.setAlignment(ParagraphAlignment.RIGHT);
    run = pgh1.createRun();
    run.setText("blah blah blah");
}

然后我尝试使用它添加页码,但我无法弄清楚

CTPageNumber pgNum = sectPr.isSetPgNumType() ? sectPr.getPgNumType() : sectPr.addNewPgNumType();
pgNum.setStart(BigInteger.valueOf(1));

请参阅 How to add page numbers in format X of Y while creating a word document using apache poi api? 了解如何在 Word 中创建页码字段。

为此,创建文本 运行 并在这些文本 运行 中插入字段 "PAGE \* MERGEFORMAT" and/or "NUMPAGES \* MERGEFORMAT"Word 的 GUI 也是这样做的。

...
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 table 单元格中。
