POI operation word merge cells

There is not much introduction to merging cells. The following is what I studied when I did word export before, and I found some information on stackoverflow.

Two key methods are noted:

[java]  view plain  copy

1. // word merge cells across columns  
2.     publicvoid mergeCellsHorizontal(XWPFTable table, int row, int fromCell, int toCell) {      
3.         for (int cellIndex = fromCell; cellIndex <= toCell; cellIndex++) {    
4.             XWPFTableCell cell = table.getRow(row).getCell(cellIndex);    
5.             if ( cellIndex == fromCell ) {    
6.                 // The first merged cell is set with RESTART merge value    
7.                 cell.getCTTc().addNewTcPr().addNewHMerge().setVal(STMerge.RESTART);    
8.             } else {    
9.                 // Cells which join (merge) the first one, are set with CONTINUE    
10.                 cell.getCTTc().addNewTcPr().addNewHMerge().setVal(STMerge.CONTINUE);    
11.             }    
12.         }    
13.     }    
14.     // word across rows and cells  
15.     publicvoid mergeCellsVertically(XWPFTable table, int col, int fromRow, int toRow) {     
16.         for (int rowIndex = fromRow; rowIndex <= toRow; rowIndex++) {    
17.             XWPFTableCell cell = table.getRow(rowIndex).getCell(col);    
18.             if ( rowIndex == fromRow ) {    
19.                 // The first merged cell is set with RESTART merge value    
20.                 cell.getCTTc().addNewTcPr().addNewVMerge().setVal(STMerge.RESTART);    
21.             } else {    
22.                 // Cells which join (merge) the first one, are set with CONTINUE    
23.                 cell.getCTTc().addNewTcPr().addNewVMerge().setVal(STMerge.CONTINUE);    
24.             }    
25.         }    
26.     }   

In addition, add the method of cell font setting:

[html]  view plain  copy

1. private void getParagraph(XWPFTableCell cell,String cellText){  
2.         CTP ctp = CTP.Factory.newInstance();  
3.         XWPFParagraph p = new XWPFParagraph(ctp, cell);  
4.         p.setAlignment (ParagraphAlignment.CENTER);  
5.         XWPFRun run = p.createRun();  
6.         run.setText(cellText);  
7.         CTRPr rpr = run.getCTR().isSetRPr() ? run.getCTR().getRPr() : run.getCTR().addNewRPr();  
8.         CTFonts fonts = rpr.isSetRFonts() ? rpr.getRFonts() : rpr.addNewRFonts();  
9.         fonts.setAscii("Fake Song Dynasty");  
10.         fonts.setEastAsia("Fake Song Dynasty");  
11.         fonts.setHAnsi("Fake Song Dynasty");  
12.         cell.setParagraph(p);  
13.     }
