Could it be that upercase characters aren't allowed in the Cell theme?
See following example:
The theme with lowercase characters gives my backcolor in the column 'mnr'. The theme with upercase characters gives a white background in the column 'TABEL'.
Here my code to create the rows.
See following example:
B4X:
MyTheme.Table("tbl1theme").AddCellTheme("ABCcenter")
MyTheme.Table("tbl1theme").Cell("ABCcenter").BackColor = ABM.COLOR_YELLOW
MyTheme.Table("tbl1theme").Cell("ABCcenter").BackColorIntensity = ABM.INTENSITY_LIGHTEN3
MyTheme.Table("tbl1theme").Cell("ABCcenter").ActiveBackColor = ABM.COLOR_YELLOW
MyTheme.Table("tbl1theme").Cell("ABCcenter").ActiveBackColorIntensity = ABM.INTENSITY_LIGHTEN1
MyTheme.Table("tbl1theme").Cell("ABCcenter").Align = ABM.TABLECELL_HORIZONTALALIGN_CENTER
MyTheme.Table("tbl1theme").AddCellTheme("abccenter")
MyTheme.Table("tbl1theme").Cell("abccenter").BackColor = ABM.COLOR_YELLOW
MyTheme.Table("tbl1theme").Cell("abccenter").BackColorIntensity = ABM.INTENSITY_LIGHTEN3
MyTheme.Table("tbl1theme").Cell("abccenter").ActiveBackColor = ABM.COLOR_YELLOW
MyTheme.Table("tbl1theme").Cell("abccenter").ActiveBackColorIntensity = ABM.INTENSITY_LIGHTEN1
MyTheme.Table("tbl1theme").Cell("abccenter").Align = ABM.TABLECELL_HORIZONTALALIGN_CENTER
The theme with lowercase characters gives my backcolor in the column 'mnr'. The theme with upercase characters gives a white background in the column 'TABEL'.
Here my code to create the rows.
B4X:
For i = 65 To 67 'Add row A,B,C
Dim rCellThemes As List
rCellThemes.Initialize
tblTelling.AddRow(i,Array As String(Chr(i), i,"","","","","","",""))
rCellThemes.AddAll(Array As String("ABCcenter","abccenter","ABCcenter","ABCcenter","abcright","abcright","abcright","abcright","abcright"))
tblTelling.SetRowThemes(rCellThemes)
