Sometimes when you are working on formatting a table in Webi, you may notice some columns all of a sudden have white borders down 1 side. It seems when you define a background color and alternating cell shading, after adding so many columns, Webi starts painting the cell borders white on one side.
I have found that Webi likes to paint white borders on columns of a certain index. If you create a plain table and set the background
to a color, then add columns one by one, the white border issue appears to happen consistently on the same column border.
This is not just a viewer issue either, exporting to PDF includes the white lines.
I have developed a work around that involves coloring the borders of a cell if it is a particular column and row.
Create a variable with the following formula:
=If Mod(LineNumber();2) = 0 Then 1 Else 0
Create a Conditional formatting rule that paints the left and right borders of a cell the color of the cell’s background if the variable you created is 1
Apply the rule to the column that has the white lines.
