JXL 生成EXCEL文件格式说明

JXL 生成EXCEL文件格式说明

1、 合并单元格

　　WritableSheet.mergeCells(int m,int n,int p,int q);

　　作用是从(m,n)到(p,q)的单元格全部合并，比如：

　　WritableSheet sheet=book.createSheet(“第一页”,0);

　　//合并第一列第一行到第六列第一行的所有单元格

　　sheet.mergeCells(0,0,5,0);

　　合并既可以是横向的，也可以是纵向的。合并后的单元格不能再次进行合并，否则会触发异常。

　　2、 行高和列宽

　　WritableSheet.setRowView(int i,int height);

　　作用是指定第i+1行的高度，比如：

　　//将第一行的高度设为200

　　sheet.setRowView(0,200);

　　WritableSheet.setColumnView(int i,int width);

　　作用是指定第i+1列的宽度，比如：

　　//将第一列的宽度设为30

　　sheet.setColumnView(0,30);
