java - 将表格边框设置为厚

我想创建一个带有粗边框的表。我已经搜索了一段时间，但似乎THICK样式不起作用。如果我选择其他样式（例如DOUBLE）就可以了，但是例如，如果我选择THIN_THICK_SMALL_GAP，则会创建两条细线。
我使用的代码是：

CTTblPr tblpro = table.getCTTbl().getTblPr();

CTTblBorders borders = tblpro.addNewTblBorders();
borders.addNewBottom().setVal(STBorder.THICK);
borders.addNewLeft().setVal(STBorder.THICK);
borders.addNewRight().setVal(STBorder.THICK);
borders.addNewTop().setVal(STBorder.THICK);
borders.addNewInsideH().setVal(STBorder.THICK);
borders.addNewInsideV().setVal(STBorder.THICK);

另一方面，如果我使用：

table.setInsideHBorder(XWPFTable.XWPFBorderType.THICK, 4, 0, "000000");
table.setInsideVBorder(XWPFTable.XWPFBorderType.THICK, 4, 0, "000000");

然后就可以了，但是我缺少桌子的外边框。

有人可以帮我吗？谢谢！

最佳答案

还不清楚为什么XWPFTable尚不具备此功能，但是如果我们查看XWPFTable.java setInsideHBorder的工作方式，那么我们可以相对容易地实现这一点。

提示：Word本身从不使用边框类型STBorder.THICK。相反，它使用STBorder.SINGLE，因为厚度由尺寸决定。这意味着没有大小的边框类型STBorder.THICK也将不可见。尺寸为24 * 1/8 pt = 3 pt的STBorder.THICK不比相同尺寸的STBorder.SINGLE厚。
