Hi Guys,

How can we set the text alignement of the table.

I tried the B4XTable1.mBase.SetTextAlignment("TOP","LEFT") but getting this error below.

Error occurred on line: 93 (Customer_Form)

I'm unsure if there is a more direct way .. also if below code is technically 'Correct'

Following example code shown here .. https://www.b4x.com/android/forum/threads/b4x-b4xtable-with-custom-cells-layout.102352/

B4X: 
B4XTable1.AddColumn("State", B4XTable1.COLUMN_TYPE_TEXT)   
B4XTable1.AddColumn("Interesting Number", B4XTable1.COLUMN_TYPE_NUMBERS)
 
B4XTable1.MaximumRowsPerPage = 10
B4XTable1.BuildLayoutsCache(10)
 
SetColumnAlignment("State", Gravity.Left)  'columnID, Alignment
SetColumnAlignment("Interesting Number", Gravity.RIGHT)  'columnID, Alignment
 
'more code ...........
   
End Sub

Sub SetColumnAlignment(columnID As String, alignmentX As Int)
 
    Dim column As B4XTableColumn = B4XTable1.GetColumn(columnID)
    For i = 1 To column.CellsLayouts.Size - 1        'starts at 1 due to header
        Dim pnl As B4XView = column.CellsLayouts.Get(i)
        Dim lbl As Label = pnl.GetView(0)   
        lbl.Gravity = Bit.Or(Gravity.CENTER_VERTICAL, alignmentX)
    Next
 
End Sub

I have multiple tables in one activity so I needed something more universal.
I also noticed that, from some reason, alignment needs to be in upper case.
So this is my solution and I hope it will help someone:

B4X: 
Sub SetColumnAlignment(tableName As B4XTable, columnID As String, alignment As String)
 
    Dim column As B4XTableColumn = tableName.GetColumn(columnID)
    For i = 1 To column.CellsLayouts.Size - 1        'starts at 1 due to header
        Dim pnl As B4XView = column.CellsLayouts.Get(i)
        pnl.GetView(0).SetTextAlignment("CENTER", alignment.ToUpperCase)
    Next
    
End Sub
