我正在尝试建立一张桌子。我需要减少 2 行之间的空间，但我无法使用row.setheight().

下面是代码：

        prepareQuotaList(table);
        CTSectPr sectPr = document.getDocument().getBody().getSectPr();

        CTPageSz pageSz = sectPr.addNewPgSz();

要在高度规则中设置表格行高，XWPFTable table还必须设置高度本身。例如：

table.getRow(0).setHeight(12*20); // row height in twentieth pt
table.getRow(0).getCtRow().getTrPr().getTrHeightArray(0).setHRule(STHeightRule.EXACT); // height rule exact

可能有以下高度规则：

AT_LEAST: 至少给定高度。如果需要，可以更高，但不能更低。

AUTO: 默认。一个默认段落高度的默认高度包括前后的间距。视内容而定，视需要而定。

EXACT: 准确的给定高度。内容可能会被删减。

请注意，不接受XWPFTableRow.setHeight的 0 值与EXACT高度规则结合使用。这会回落到默认AUTO高度。

根据您的代码示例：

...
    private static void prepareQuotaList(XWPFTable table) {
        int count = 0;
        for (int row = 0; row < 4; row++) {
            XWPFTableRow tableRow = table.getRow(row);
            tableRow.setHeight(12*20); // row height = 12 pt
            tableRow.getCtRow().getTrPr().getTrHeightArray(0).setHRule(STHeightRule.EXACT); // height rule exact
            for (int col = 0; col < 3; col++) {
                setCellBorders(tableRow.getCell(col), new STBorder.Enum[]{STBorder.NIL, STBorder.NIL, STBorder.NIL, STBorder.NIL});
            }
...
    }
...

如上所述，只有三个高度规则是可能的。因此，如果目标是让表格行与其内容一样高，但不是更多或更少，那么AUTO必须使用高度规则。然后段落的高度决定了行高。请注意，XWPFParagraph 可能在文本行之前、之间和之后设置了间距。所以你可能需要设置：

...
paragraph.setSpacingAfter(0);
paragraph.setSpacingBetween(1); // don't set this 0
paragraph.setSpacingBefore(0);
...

这必须为每个已经包含段落的表格单元格设置。因此，如果整个表都需要，那么：

XWPFTable table = document.createTable(4, 8);
for (XWPFTableRow row : table.getRows()) {
 for (XWPFTableCell cell : row.getTableCells()) {
  for (XWPFParagraph p : cell.getParagraphs()) {
   p.setSpacingAfter(0);
   p.setSpacingBetween(1); // don't set this 0
   p.setSpacingBefore(0);
  }
 }
}
