Have you followed the grid layout instructions?
From what you show, many rows have a background color applied. Use the BuildTheme () for that and add the param to the row ("bg" - for example below).
theme.Table("tbltheme").AddCellTheme("bg")
theme.Table("tbltheme").Cell("bg").BackColor = ABM.COLOR_BLUEGREY
theme.Table("tbltheme").Cell("bg").ForeColor = ABM.COLOR_WHITE
theme.Table("tbltheme").Cell("bg").Align = ABM.TABLECELL_HORIZONTALALIGN_LEFT
The first row is simple:
this_example.Content.AddRowsM(1, True, 0, 0, "bg").AddCellsOS(1, 0, 0, 0, 12, 12, 12, "bg") ' not exactly correct but you get the hint..
(or other row and cell calls that produce a like result)
The second row has 12 cells. You can:
this_example.Content.AddRowsM(1 , True, 0, 0, "").AddCellsOS(1, 0, 0, 0, 6, 6, 6, "").AddCellsOS(1, 0, 0, 0, 6, 6, 6, "")... up to 12 cells, yet the "6" should equal 1 here, since 12 cells are being applied (12 / number of cells = value to use).
Seems like row 9 (Gray) you want to show something in that cell. Refer to row 9, cell 2 in your call.
Best way is to study the provided examples and, experiment and grow your knowledge from there.
It is difficult to explain what to use in every situation since one cannot determine your specific outcome.
In ABM, as I find, there are many ways to skin this cat. What is appropriate depends on the desired outcome.
