用COM操作自动生成excel，怎样控制单元格的高度，宽度，以及文字居中？？？
--------------------编程问答-------------------- 我自己顶，顶起！ --------------------编程问答-------------------- Rows("4:4").RowHeight = 61.5
//在一下程序的基础下，怎样制单元格的高度，宽度，以及文字居中？？？请高手指点，写详细点，分不多了,谢谢各位

网上查过，没有用，你在我上面的程序基础上改下 --------------------编程问答-------------------- 你都沒定義寬度怎么設？ --------------------编程问答-------------------- 怎么定义，请贴代码 --------------------编程问答-------------------- 不控制单元格的高度宽度，那我如果要控制整列的宽度总行吧，怎么控制贴代码
谢谢！ --------------------编程问答-------------------- 在用Excel作报表的时候，可能需要操作单元格的边框和填充颜色和纹理等操作，下面的代码说明如何设置选中的单元格的填充纹理和边框
