[简单]docx4j表格新增行(Tr)

       从本篇博文开始，不提供全部的代码，详细代码见http://53873039oycg.iteye.com/blog/2194479。关键代码如下:

     

/**
	 * @Description: 在表格指定位置新增一行,默认居中
	 */
	public void addTrByIndex(Tbl tbl, int index) {
		addTrByIndex(tbl, index, STVerticalJc.CENTER, JcEnumeration.CENTER);
	}

	/**
	 * @Description: 在表格指定位置新增一行(默认按表格定义的列数添加)
	 */
	public void addTrByIndex(Tbl tbl, int index, STVerticalJc vAlign,
			JcEnumeration hAlign) {
		TblGrid tblGrid = tbl.getTblGrid();
		Tr tr = new Tr();
		if (tblGrid != null) {
			List<TblGridCol> gridList = tblGrid.getGridCol();
			for (TblGridCol tblGridCol : gridList) {
				Tc tc = new Tc();
				setTcWidth(tc, tblGridCol.getW().toString());
				if (vAlign != null) {
					// 垂直居中
					setTcVAlign(tc, vAlign);
				}
				P p = new P();
				if (hAlign != null) {
					PPr pPr = new PPr();
					Jc jc = new Jc();
					// 单元格居中对齐
					jc.setVal(hAlign);
					pPr.setJc(jc);
					p.setPPr(pPr);
				}
				R run = new R();
				p.getContent().add(run);
				tc.getContent().add(p);
				tr.getContent().add(tc);
			}
		} else {
			// 大部分情况都不会走到这一步
			Tr firstTr = getTblAllTr(tbl).get(0);
			int cellSize = getTcCellSizeWithMergeNum(firstTr);
			for (int i = 0; i < cellSize; i++) {
				Tc tc = new Tc();
				if (vAlign != null) {
					// 垂直居中
					setTcVAlign(tc, vAlign);
				}
				P p = new P();
				if (hAlign != null) {
					PPr pPr = new PPr();
					Jc jc = new Jc();
					// 单元格居中对齐
					jc.setVal(hAlign);
					pPr.setJc(jc);
					p.setPPr(pPr);
				}
				R run = new R();
				p.getContent().add(run);
				tc.getContent().add(p);
				tr.getContent().add(tc);
			}
		}
		if (index >= 0&&index<tbl.getContent().size()) {
			tbl.getContent().add(index, tr);
		} else {
			tbl.getContent().add(tr);
		}
	}
	
	/**
	 * @Description: 得到行的列数
	 */
	public int getTcCellSizeWithMergeNum(Tr tr) {
		int cellSize = 1;
		List<Tc> tcList = getTrAllCell(tr);
		if (tcList == null || tcList.size() == 0) {
			return cellSize;
		}
		cellSize = tcList.size();
		for (Tc tc : tcList) {
			TcPr tcPr = getTcPr(tc);
			GridSpan gridSpan = tcPr.getGridSpan();
			if (gridSpan != null) {
				cellSize += gridSpan.getVal().intValue() - 1;
			}
		}
		return cellSize;
	}
