B4J Question [ABMaterial] Wht cann't put into the center of cell

[jinyistudio]

Hi
I put abmbutton(btnsel) into a cell. Why it cann't align to the center of cell !?

theme.AddCellTheme("cellcenter")
   theme.Cell("cellcenter").Align = ABM.CELL_ALIGN_CENTER
   theme.Cell("cellcenter").VerticalAlign = True

 

[mindful]

You need to make the cell fixed height so that the button will center it self.

page.Cell(1, 2).SetFixedHeight(80, False)
