Hi

Is there a way to set the visibility of a B4XTable column?
I have found some examples of 'hiding' columns but they just seem to be deleting it; I want the column to exist but not be visible.
Saw another example that suggested setting the Width to zero but it seems to always be set to zero and explicitly setting it did not help.
CalculatedWidth seems to have a value but setting that to zero has no effect either.

Many thanks

You can hide it and still able to access the map values.

B4X: 
B4XTable1.SetData(Data)
B4XTable1.VisibleColumns.RemoveAt(B4XTable1.VisibleColumns.IndexOf(HiddenColumn))
B4XTable1.Refresh

You can change column width to 1 dip..
Click to expand...
Thanks; I did find that suggestion but it does not seem to work.
Code:: 
    Log("Before > Width: " & IDColumn.Width)
    IDColumn.Width = 1dip
    Log("After > Width: " & IDColumn.Width)

Log: 
Before > Width: 0
After > Width: 0

But the column is still visible.

Hopefully, @Magma or @aeric took care of your problem, but If you are still looking for a solutio, see my code (it works) in post #5 or Jeffrey's code in post #8 in this thread link:
