Setting Table borders to THICK

问题

I would like to create a table with thick borders. I've been searching for a while but it seems that the style THICK does not work. If I select other styles such as DOUBLE it's fine but for instance, if I select THIN_THICK_SMALL_GAP it creates two thin lines. The code I'm using is:

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);

On the other hand, if I use:

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

Then it works, but I'm missing the outer border of the table.

Can anyone help me with this please? Thank you!

回答1:

Not clear why XWPFTable does not have this already but if we look at XWPFTable.java how the setInsideHBorder works, then we can implementing this relatively easy.

Hint : Word itself never uses border type STBorder.THICK. Instead it uses STBorder.SINGLE because the thickness is determined by the size. That means that border type STBorder.THICK without size is also not visible. And STBorder.THICK with size 24 * 1/8 pt = 3 pt is not thicker than STBorder.SINGLE with the same size.

Example:

import java.io.FileOutputStream;

import org.apache.poi.xwpf.usermodel.*;
import org.apache.poi.xwpf.usermodel.XWPFTable.XWPFBorderType;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.*;

import java.util.EnumMap;

import java.math.BigInteger;

public class CreateWordTableBorders {

 private static EnumMap<XWPFBorderType, STBorder.Enum> xwpfBorderTypeMap;

  // populate enum map
  xwpfBorderTypeMap = new EnumMap<XWPFBorderType, STBorder.Enum>(XWPFBorderType.class);
  xwpfBorderTypeMap.put(XWPFBorderType.NIL, STBorder.Enum.forInt(STBorder.INT_NIL));
  xwpfBorderTypeMap.put(XWPFBorderType.NONE, STBorder.Enum.forInt(STBorder.INT_NONE));
  xwpfBorderTypeMap.put(XWPFBorderType.SINGLE, STBorder.Enum.forInt(STBorder.INT_SINGLE));
  xwpfBorderTypeMap.put(XWPFBorderType.THICK, STBorder.Enum.forInt(STBorder.INT_THICK));
  xwpfBorderTypeMap.put(XWPFBorderType.DOUBLE, STBorder.Enum.forInt(STBorder.INT_DOUBLE));
  xwpfBorderTypeMap.put(XWPFBorderType.DOTTED, STBorder.Enum.forInt(STBorder.INT_DOTTED));
  xwpfBorderTypeMap.put(XWPFBorderType.DASHED, STBorder.Enum.forInt(STBorder.INT_DASHED));
  xwpfBorderTypeMap.put(XWPFBorderType.DOT_DASH, STBorder.Enum.forInt(STBorder.INT_DOT_DASH));
 }

 private enum BorderPosition {
  TOP, BOTTOM, LEFT, RIGHT
 }

 private static void setTableBorder(BorderPosition position, XWPFTable table, XWPFBorderType type,
