需要减少apache poi单词中2个单元格之间的空格

Question

我正在尝试构建一个表。我需要减少2行之间的空间，但我无法使用row.setheight()来实现结果。

以下是代码：

要在XWPFTable table中设置表行高度，还必须在高度本身之外设置高度规则。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：至少是给定的高度。如果需要，可以更高，但不能更低。

AUTO：默认值。一个默认段落高度的默认高度，包括前后间距。视需要而定，取决于内容。

EXACT：精确给定的高度。内容可能会被剪切掉。

请注意，XWPFTableRow.setHeight的0值不会与EXACT高度规则结合使用。然后，这将回落到默认的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，只有三个可能的高度规则。因此，如果目标是使表行与其内容一样高，但不是更多或更少，那么必须使用高度规则AUTO。然后段落的高度决定行的高度。请注意，XWPFParagraph可能在文本行之前、之间和之后设置了间距。所以你可能必须设置：

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

必须为已包含段落的每个表格单元格设置此项。因此，如果需要整个表格，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);
}
}
}
