    SubName: SetTableHeaderWrap

    Allows the table view header text to wrap.

    Sub SetTableHeaderWrap(Table As JavaObject, PrefHeight As Int)

    Dim HeaderRow As Pane = Table.RunMethod("lookup",Array("TableHeaderRow"))
    For Each N As JavaObject In HeaderRow.GetAllViewsRecursive
    If N Is Label Then
    Dim NL As Label = N
    If PrefHeight <> -1 Then NL.PrefHeight = PrefHeight
    'Seems to lose the text centering
    End If
    End Sub
    Set the PrefHeight to -1 to leave it unchanged.

    Dependencies: JavaObject, CSSUtils

    CSSUtils is available here: https://www.b4x.com/android/forum/threads/class-cssutils.61824/

    Nice. I recommend using CSSUtils.SetProperty instead of appending the attribute to the style. The advantage of CSSUtils.SetProperty is that it will replace the existing attribute (if such exists).
