给您帮助过的内容您看过试过吗？帖子回复了吗？
您非得要固执到底，没法帮您！
您也不想想，您这样先列后行地生成，每设置一个列标题，就要将rows所有行往专业报表中写一遍，根据您目前的字段数，这些行各字段值被重复写了9遍，再生成所有区域的拍表，其效率何等低下！既然为您改为先行后列的嵌套遍历，就有我的道理，您自己都不关注，怎能靠别人上心！

请仔细分析我3楼给的提示，您的代码效率太低，作为开发者，应当优化改进，不仅仅是可以了！

提示这么明显了，学会调试判断错误的原因。不是别人给了一段代码，就只能被动的等别人来改

Dim ColNames As String() = New String() {"区域楼层", "区域名称", "订单类别", "产品名称", "图片", "工艺描述", "销售单价", "计价单位", "数量", "金额小计", "备注" }
rt.Rows.Count

上面这一行rt.Rows.Count是我复制进去备用的，忘了删，自己删除嘛！

前面重新编辑了，自己要去消化，而不仅是拿来用思维！

提示一样的明显，都不是复杂的错误，基本是手误输错的....

1、确实如蓝版所说，遍历语句手误：For r应为For Each r
2、刚使用新的代码编辑器，还不是很习惯，将文字水平对齐搞成了上下对齐，手写了left，犯了这种低级错误；

您自己要自己要学会识别错误位置和改错才行，改这个并不难！
