老师好，我想在下面再增加一个判断条件（房屋主体），房屋主体下有：
一号楼
二号楼
三号楼
If e.DataCol.Name = "项目" Then
If e.DataCol.Name = "项目" OrElse e.DataCol.Name ="抄表日期" Then
Dim dr1 As DataRow = e.DataTable.Find("项目='" & e.NewValue & "' and 抄表日期 is not null and _sortkey <" & e.DataRow("_sortkey"), "_sortkey desc")
Dim sl As Double
Dim st As Decimal=0
If dr1 IsNot Nothing Then
sl = dr1("总表_本期读数")
st = dr1("_sortkey")
e.DataRow("总表_上期读数") = sl
End If
Dim dr2 As DataRow = e.DataTable.find("项目='" & e.NewValue & "' and 购气_数量 is not null and _sortkey <" & e.DataRow("_sortkey") & " and _sortkey > " & st, "_sortkey desc")
If dr2 IsNot Nothing Then
e.DataRow("总表_上期读数") = sl + dr2("购气_数量")
End If
End If
End If
