iLogic Table formatting error

[S7RM7RPR]

I am attempting to change the text justification in a table. In the API help I've fround the code below and I've been scouring the forms and no one seems to have a problem but when I'm running it I get "The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))"

If I comment out the justifcation line it works just fine.

    '  a reference to the drawing document.
    ' This assumes a drawing document is active.
    Dim oDrawDoc As DrawingDocument
     oDrawDoc = ThisApplication.ActiveDocument
    
    '  a reference to the active sheet.
    Dim oSheet As Sheet
     oSheet = oDrawDoc.ActiveSheet
    
    '  the column titles
    Dim oTitles(2) As String
    oTitles(0) = "Part Number"
    oTitles(1) = "Quantity"
    oTitles(2) = "Material"
    
    '  the contents of the custom table (contents are  row-wise)
    Dim oContents(8) As String
    oContents(0) = "1"
    oContents(1) = "1"
    oContents(2) = "Brass"
    oContents(3) = "2"
    oContents(4) = "2"
    oContents(5) = "Aluminium"
    oContents(6) = "3"
    oContents(7) = "1"
    oContents(8) = "Steel"
    
    '  the column widths (defaults to the column title width if not specified)

    oColumnWidths(2) = 4
      
    ' Create the custom table
    Dim oCustomTable As CustomTable
     oCustomTable = oSheet.CustomTables.Add("My Table", ThisApplication.TransientGeometry.CreatePoint2d(15, 15), 3, 3, oTitles, oContents, oColumnWidths)
                                        
    ' Change the 3rd column to be left justified.
    oCustomTable.Columns.Item(3).ValueHorizontalJustification = kAlignTextCenter 
    
    ' Create a table format object
    Dim oFormat As TableFormat
    oFormat = oSheet.CustomTables.CreateTableFormat

    '  outside line weight.
    oFormat.InsideLineWeight = 0.025
    oFormat.OutsideLineWeight = 0.025
    
    ' Modify the table formats
    oCustomTable.OverrideFormat = oFormat

Slightly different question. Can anyone tell me where to put "CustomTable.Title()" so I can turn off the table title?

The inventor API help is a bloody joke. Finally dug up a solution.

oCustomTable.Columns.Item(1).ValueHorizontalJustification = HorizontalTextAlignmentEnum.kAlignTextLeft
