B4J Question Tableview extracting text from a column

[tsteward]

I have a tableview and would like to total the figures in column 4 and display in a label below the table.
Each cell of the table contains a label to allow users to be able to change values.

Not sure how to cycle through each row extracting the value from column 4

Thank you

Something like:

Dim total As Int
For Each row() As Object in TableView1.Items
 Dim lbl As Label = row(3)
 if IsNumber(lbl.Text) Then total = total + lbl.Text
Next
