Display two columns in combobox

I have the following code that shows in combobox "cboCust" the information of ColumnB, how can I modify the code to show in combobox ColumnB and C?

Private Sub UserForm_Initialize()

'multiple columns combobox

    With cboCust
        .ColumnCount = 2
        .List = Range("tblClients").ListObject.ListColumns(2).DataBodyRange.Value
        .ColumnWidths = "70 pt;30 pt"
    End With

End Sub

That worked great thank you so much!

AlphaFrog, can you please help me to adjust the code if I want to select non-adjacent columns such as B, M and T?

One way would be to set the ColumnCount to 19 (Column B to Column T) and set the ColumnWidths for the Columns not needed to 0.

.ColumnWidths = "70;0;0;0;0;0;0;0;0;0;0;30;0;0;0;0;0;0;45"

Or you can copy the needed Columns into another Sheet (Hidden or VeryHidden?) and use that.

thank you that worked
