JXL 生成EXCEL文件格式說明

JXL 生成EXCEL文件格式說明

1、 合併單元格 
　　WritableSheet.mergeCells(int m,int n,int p,int q); 
　　作用是從(m,n)到(p,q)的單元格全部合併，比如： 
　　WritableSheet sheet=book.createSheet(“第一頁”,0); 
　　//合併第一列第一行到第六列第一行的所有單元格 
　　sheet.mergeCells(0,0,5,0); 
　　合併既可以是橫向的，也可以是縱向的。合併後的單元格不能再次進行合併，否則會觸發異常。 
　　2、 行高和列寬 
　　WritableSheet.setRowView(int i,int height); 
　　作用是指定第i+1行的高度，比如： 
　　//將第一行的高度設爲200 
　　sheet.setRowView(0,200); 
　　WritableSheet.setColumnView(int i,int width); 
　　作用是指定第i+1列的寬度，比如： 
　　//將第一列的寬度設爲30 
　　sheet.setColumnView(0,30);
