如题:交叉统计不显示数据(手工编写,如果某条件列有空值,则对应的行统计数据也显示为空)
比如,用气明细 表中,类别列里,个别行字段为空值,则在 气量统计 表中,统计各日期下的数据都为空.....同样方式在EXCEL透视表中,是可以显示数据的.
代码如下:
Dim dtb As New DataTableBuilder("气量统计")
dtb.AddDef("排序", Gettype(String), 50)
dtb.AddDef("位置", Gettype(String), 50)
dtb.AddDef("回路名称", Gettype(String), 50)
dtb.AddDef("类别", Gettype(String), 50)
'dtb.AddDef("合并字符",Gettype(String),100)
Dim prds As List(of String) = DataTables("用气明细").GetValues("日期")
For Each prd As Date In prds
dtb.AddDef(prd, Gettype(Double))
Next
dtb.Build()
For Each cus() As String In dt.GetValues("排序|位置|回路名称|类别")
Dim dtbr As DataRow = DataTables("气量统计").AddNew()
dtbr("排序") = cus(0)
dtbr("位置") = cus(1)
dtbr("回路名称") = cus(2)
dtbr("类别") = cus(3)
'dtbr("合并字符") = cus(0) & cus(1) & cus(2) & cus(3)
For Each prd As Date In prds
dtbr(prd) = dt.Compute("Sum(实际用气量)","排序 = '" & cus(0) & "'and 位置 = '" & cus(1) & "' and 回路名称 = '" & cus(2) & "' and 类别 ='" & cus(3) & "' And [日期] = '" & prd.Date & "'")
Next
Next
MainTable = Tables("气量统计")
