HWPF-POI:用java在word中插入表格 [英] HWPF-POI: inserting table in word with java

问题描述

我想用 POI-HWPF(例如 doc 格式)在 Word 中创建一个表格.我的示例代码是:

I want to create a table in Word with POI-HWPF (e.g. doc format). My example code is:

Table table = document.getRange().insertTableBefore((short) 2, 2);

表格已插入，但我看不到 - 好像表格的宽度为 0.有人可以帮我吗?

The table is inserted, but I can't see it - as if the table has the width 0. Can anybody help me?

推荐答案

这个 旧的错误报告应该让你知道如何去做.

The file linked in this old bug report should give you an idea how to do it.

所以本质上:您可能需要添加一些内容(即单元格中的一个段落)，以便 Word 可以呈现一些内容.

So in essence: You probably need to add some content (i.e. a paragraph in a cell) so that Word has something to render.

这是错误报告中使用的示例代码:

Here is the example code used in the bug report:

private static void test (int rows, int columns) throws Exception {
    // POI apparently can't create a document from scratch,
    // so we need an existing empty dummy document
    POIFSFileSystem fs = new POIFSFileSystem(new FileInputStream("empty.doc"));
    HWPFDocument doc = new HWPFDocument(fs);

    Range range = doc.getRange();
    Table table = range.insertBefore(new TableProperties(columns), rows);

    for (int rowIdx=0; rowIdx<table.numRows(); rowIdx++) {
        TableRow row = table.getRow(rowIdx);
        System.out.println("row "+rowIdx);
        for (int colIdx=0; colIdx<row.numCells(); colIdx++) {
            TableCell cell = row.getCell(colIdx);
            System.out.println("column "+colIdx+", num paragraphs "+cell.numParagraphs());
            try {
                Paragraph par = cell.getParagraph(0);
                par.insertBefore(""+(rowIdx*row.numCells()+colIdx));
            } catch (Exception ex) {
                ex.printStackTrace();
            }
        }
    }
