POI操作word合并单元格

对于合并单元格的介绍不怎么多，下面是之前做word导出的时候研究的，在stackoverflow查到了点资料。

记录下两个关键方法：

// word跨列合并单元格
	public  void mergeCellsHorizontal(XWPFTable table, int row, int fromCell, int toCell) {  
        for (int cellIndex = fromCell; cellIndex <= toCell; cellIndex++) {  
            XWPFTableCell cell = table.getRow(row).getCell(cellIndex);  
            if ( cellIndex == fromCell ) {  
                // The first merged cell is set with RESTART merge value  
                cell.getCTTc().addNewTcPr().addNewHMerge().setVal(STMerge.RESTART);  
            } else {  
                // Cells which join (merge) the first one, are set with CONTINUE  
                cell.getCTTc().addNewTcPr().addNewHMerge().setVal(STMerge.CONTINUE);  
            }  
        }  
    }  
	// word跨行并单元格
	public void mergeCellsVertically(XWPFTable table, int col, int fromRow, int toRow) {  
        for (int rowIndex = fromRow; rowIndex <= toRow; rowIndex++) {  
            XWPFTableCell cell = table.getRow(rowIndex).getCell(col);  
            if ( rowIndex == fromRow ) {  
                // The first merged cell is set with RESTART merge value  
                cell.getCTTc().addNewTcPr().addNewVMerge().setVal(STMerge.RESTART);  
            } else {  
                // Cells which join (merge) the first one, are set with CONTINUE  
                cell.getCTTc().addNewTcPr().addNewVMerge().setVal(STMerge.CONTINUE);  
            }  
        }  
    } 

另外加上单元格字体设置的方法：

private void getParagraph(XWPFTableCell cell,String cellText){
		CTP ctp = CTP.Factory.newInstance();
		XWPFParagraph p = new XWPFParagraph(ctp, cell);
		p.setAlignment(ParagraphAlignment.CENTER);
        XWPFRun run = p.createRun();
        run.setText(cellText);
        CTRPr rpr = run.getCTR().isSetRPr() ? run.getCTR().getRPr() : run.getCTR().addNewRPr();
        CTFonts fonts = rpr.isSetRFonts() ? rpr.getRFonts() : rpr.addNewRFonts();
        fonts.setAscii("仿宋");
        fonts.setEastAsia("仿宋");
        fonts.setHAnsi("仿宋");
        cell.setParagraph(p);
	}
