SSRS Tablix border size inconsistent

Question

I am using a totally standard tablix table (no embedded sub-tables or anything) in a SSRS report with a 1pt solid border around all cells which looks as I would expect during preview with consistent borders.

But when I deploy the report and run it, the borders are inconsistent with a thicker horizontal border line appearing every two or three rows, and the external borders also being inconsistent.

I see the same in Edge and Chrome.

Any ideas? example here

Answer 1

Try changing the border width to 0.5pt, this worked for me.

Answer 2

I had the same problem. I solved it by avoiding overlapping of borders of subsequence cells. Mainly you don't need top border at all. And you don't need right border for all cells except the right most one.

Here is my settings looks like: For all cells: Boarder Style Setting For All Cells

For right most cell:

Boarder Style Setting For Right Most Cell

The border of my top most row is covered by border of header row. Hope it helps.
