设置Apache POI XWPFTable表的外边框？

我需要设置Apache POI XWPFTable表的外边框.我知道下面的命令设置了insade border,但是没有找到设置外边框的方法.

table.setInsideHBorder( XWPFBorderType.SINGLE, 4, 0, "FF0000");

有帮助吗？提前致谢!

我找到了:

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

CTTblBorders borders = tblpro.addNewTblBorders();
borders.addNewBottom().setVal(STBorder.SINGLE); 
borders.addNewLeft().setVal(STBorder.SINGLE);
borders.addNewRight().setVal(STBorder.SINGLE);
borders.addNewTop().setVal(STBorder.SINGLE);
//also inner borders
borders.addNewInsideH().setVal(STBorder.SINGLE);
borders.addNewInsideV().setVal(STBorder.SINGLE);
