changing optic of vertical gridlines to match background color of cells

[Daniela]

Hi!
I have a problem with my gridline-color/appearance when I change the color of the colum in a table.
As you can see on the attached screenshot I have a table as rowdetails in another table. The rowdetails table has the problem.
The rows should have a light blue color without any horizontal gridlines so that the table appears to have one cell with tabs. So I defined the table as in the code below.

When having a closer look at the screenshot (zoom in, if you don't regocnize it) you can see, that there is a small "white" line (in color of the standard table color), which should not be there. I tried to set the background of the table itself to the same color but this would not help. The only way I don't see the white line, is to let the background color of the columns as it is. But I need the light blue color, so this is no option for me.

Do anyone know how I set the gridlines color or the background of the table so, that I get my table in light blue without any white line between the columns?

Hi Daniela,

You may achieve this result by predefining the template of GridViewCell, please refer to this help article.
