mark 合并模式

Dim t As Table = Tables("表a")
Dim cs As String() = {"第一列", "第二列", "第五列"}

\'取消合并
Dim ls As new List(of object)
For Each r As object In t.Grid.MergedRanges
        ls.add(r)
Next
For Each r As object In ls
    t.Grid.MergedRanges.Remove(r)
Next

\'设置合并
For i As Integer = 0 To cs.length-1
    Dim top As Integer = 0
    For j As Integer = 1 To t.Rows.count-1
        Dim r1 As Row = t.Rows(j-1)
        Dim r2 As Row = t.Rows(j)
        Dim same As Boolean = True
        For k As Integer = 0 To i
            If r1(cs(k)) <> r2(cs(k)) Then
                same = False
                Exit For
            End If
        Next
       
        If same = False  Then
            t.Grid.AllowMerging = C1.Win.C1FlexGrid.AllowMergingEnum.Custom
            Dim rng As C1.Win.C1FlexGrid.CellRange = t.Grid.GetCellRange(top+t.HeaderRows, t.cols(cs(i)).Index+1, j+t.HeaderRows-1, t.cols(cs(i)).Index+1)
            t.Grid.MergedRanges.add(rng)
           
            Top = j
        ElseIf j = t.rows.count-1 Then
            Dim rng As C1.Win.C1FlexGrid.CellRange = t.Grid.GetCellRange(top+t.HeaderRows, t.cols(cs(i)).Index+1, j+t.HeaderRows, t.cols(cs(i)).Index+1)
            t.Grid.MergedRanges.add(rng)
        End If
    Next
   
Next

这里改成自己的表和列

Dim t As Table = Tables("表a")
Dim cs As String() = {"第一列", "第二列", "第五列"}
