java - 将表格边框设置为厚

问题描述

我想创建一个带有粗边框的表格。我一直在寻找一段时间，但似乎 THICK 风格不起作用。如果我选择其他样式，例如 DOUBLE，那很好，但例如，如果我选择 THIN_THICK_SMALL_GAP，它会创建两条细线。我正在使用的代码是：

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");

然后它可以工作，但我错过了表格的外边框。

任何人都可以帮我解决这个问题吗？谢谢！

解决方案

不清楚为什么XWPFTable还没有这个，但是如果我们看看XWPFTable.java是如何setInsideHBorder工作的，那么我们可以相对容易地实现这个。

提示：Word它本身从不使用边框类型STBorder.THICK。相反，它使用STBorder.SINGLE，因为厚度是由大小决定的。这意味着STBorder.THICK没有大小的边框类型也不可见。并且STBorder.THICK尺寸为 24 * 1/8 pt = 3 pt 并不比STBorder.SINGLE相同尺寸的厚。

例子：

import java.io.FileOutputStream;

  xwpfBorderTypeMap.put(XWPFBorderType.NIL, STBorder.Enum.forInt(STBorder.INT_NIL));
  xwpfBorderTypeMap.put(XWPFBorderType.NONE, STBorder.Enum.forInt(STBorder.INT_NONE));
