首先，列必须是数值型

然后参考：http://www.foxtable.com/help/topics/0393.htm

用这个后选择字符型的列的数字后出现死循环怎么破？

写到系统SystemIdle事件

Dim str1 As String = ""
Dim t As Table = CurrentTable
Str1 = Str1 & "计数:" & t.Aggregate(AggregateEnum.Count, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
Str1 = Str1 & "累计:" & t.Aggregate(AggregateEnum.Sum, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
Str1 = Str1 & "平均:" & t.Aggregate(AggregateEnum.Average, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
Str1 = Str1 & "最大:" & t.Aggregate(AggregateEnum.Max, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
Str1 = Str1 & "最小:" & t.Aggregate(AggregateEnum.Min, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
Str1 = Str1 & "标准差:" & t.Aggregate(AggregateEnum.Std, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
Str1 = Str1 & "总体标准差:" & t.Aggregate(AggregateEnum.StdPop, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
Str1 = Str1 & "方差:" & t.Aggregate(AggregateEnum.Var, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
Str1 = Str1 & "总体方差:" & t.Aggregate(AggregateEnum.VarPop, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "

StatusBar.Message3 = str1

用这个方法后出现这样的

你的值太大照成的，尽量不要统计字符列，不然会报错

Dim str1 As String = ""
Dim t As Table = CurrentTable
Dim hadString As Boolean = False
For i As Integer = t.LeftCol To t.RightCol
    If t.cols(i).IsString Then
        hadString = True
        Exit For
    End If
Next
Str1 = Str1 & "计数:" & t.Aggregate(AggregateEnum.Count, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
If hadString = False Then
    Str1 = Str1 & "累计:" & t.Aggregate(AggregateEnum.Sum, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
    Str1 = Str1 & "平均:" & t.Aggregate(AggregateEnum.Average, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
    Str1 = Str1 & "最大:" & t.Aggregate(AggregateEnum.Max, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
    Str1 = Str1 & "最小:" & t.Aggregate(AggregateEnum.Min, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
    Str1 = Str1 & "标准差:" & t.Aggregate(AggregateEnum.Std, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
    Str1 = Str1 & "总体标准差:" & t.Aggregate(AggregateEnum.StdPop, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
    Str1 = Str1 & "方差:" & t.Aggregate(AggregateEnum.Var, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
    Str1 = Str1 & "总体方差:" & t.Aggregate(AggregateEnum.VarPop, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
End If

StatusBar.Message3 = str1

您这个代码还是报错我这样修改了一下测试可用不会报错
If CurrentTable.Cols(CurrentTable.ColSel).IsNumeric Then
Dim str1 As String = ""
Dim t As Table = CurrentTable
Str1 = Str1 & "计数:" & t.Aggregate(AggregateEnum.Count, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
Str1 = Str1 & "累计:" & t.Aggregate(AggregateEnum.Sum, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
Str1 = Str1 & "平均:" & t.Aggregate(AggregateEnum.Average, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
\'Str1 = Str1 & "最大:" & t.Aggregate(AggregateEnum.Max, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
\'Str1 = Str1 & "最小:" & t.Aggregate(AggregateEnum.Min, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
\'Str1 = Str1 & "标准差:" & t.Aggregate(AggregateEnum.Std, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
\'Str1 = Str1 & "总体标准差:" & t.Aggregate(AggregateEnum.StdPop, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
\'Str1 = Str1 & "方差:" & t.Aggregate(AggregateEnum.Var, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
\'Str1 = Str1 & "总体方差:" & t.Aggregate(AggregateEnum.VarPop, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "
StatusBar.Message3 = str1

Else
Dim str1 As String = "非数值型,无法统计"
StatusBar.Message3 = str1
End If

5楼代码我测试没问题，当然，能用就好。

Str1 = Str1 & "计数:" & t.Aggregate(AggregateEnum.Count, t.TopRow, t.LeftCol, t.BottomRow, t.RightCol) & " "

上面代码放在判断语句外还是出错，放在判断语句内就不出错了，但“计数”就统计不出来了
