主题：[求助]列类型转换问题

方法一：新增一列【时长】，然后把【处理时长】整列的数据，拷贝粘贴过去；

方法二：参考代码

Dim t As Table = Tables("表A")
Dim d As Double
Dim str As String = "-1,"
For Each r As Row In t.rows
    If r("第二列") > "" AndAlso Double.TryParse(r("第二列"), d) = False Then
        str &= r("_Identify") & ","
    End If
Next
t.filter = "_Identify in (" & str.trim(",") & ")"
