[VBA]Join two tables with any number of columns in a easy format

https://github.com/walter426/VbaUtilities/blob/master/SqlUtilities.bas
In order to join two tables into one, the SQL syntax is very complicated.
So I wrote below function to reduce the complexity.



''Create table which are joined from two tables
Public Function CreateTbl_JoinTwoTbl(Tbl_src_1_name As String, Tbl_src_2_name As String, JoinCond As String, ColSet_Join_1 As Variant, ColSet_Join_2 As Variant, Tbl_des_name As String, Optional ColSet_src_1 As Variant = Null, Optional ColSet_src_2 As Variant = Null, Optional ColSet_Order As Variant = Null) As String
    On Error GoTo Err_CreateTbl_JoinTwoTbl
    
    Dim FailedReason As String

    If TableExist(Tbl_src_1_name) = False Then
        FailedReason = Tbl_src_1_name & "does not exist!"
        GoTo Exit_CreateTbl_JoinTwoTbl
    End If
    
    If TableExist(Tbl_src_2_name) = False Then
        FailedReason = Tbl_src_2_name & "does not exist!"
