主题：[求助]专业报表因隐藏列出错（已解决）

在按钮代码的第一行加了一行代码，移除隐藏列 "jq"后，可以打开表，但是重新加载表后，提示找不到"jq"列，因为"jq"列用于排序的，不能省缺。还是要想其他方法来解决，请各位老师指教，谢谢！！

 

 

Tables("存款明细").Cols.Remove("jq")

如果只有一列要隐藏,最简单的办法就是将此列移到最后,然后将这代码改成如下:

 

原来: For c As Integer = 0 To tb.Cols.Count - 1  '逐列设置和填入内容

 

 

 改为:For c As Integer = 0 To tb.Cols.Count - 2  '逐列设置和填入内容

谢谢yangming老师的指教，此方法可行，已圆满解决问题，再次表示衷心感谢！！

 

这样不严谨吧？

其实你要找到真正问题所在才行，那种方法并不可取。

回czy老师，根据您的方案修改，仍然出现原来的错误提示。出现错误的原因已经明确，就是因为隐藏列，有什么更好的方法来解决，还望指教。谢谢！！

不会啊。

你将下面的代码放到系统模板的订单表中测试一下：
