If you’re viewing your exported PDF in Adobe Acrobat, you may notice that some table borders:
-
Look uneven
-
Appear thinner in certain columns
-
Seem to disappear entirely
This is caused by how Adobe Acrobat renders thin lines in PDFs. The borders are not missing — they are displayed incorrectly by the viewer.
Why this happens
Adobe Acrobat sometimes renders very thin table borders inconsistently at certain zoom levels. This can create the impression that lines are missing or have different thicknesses.
The issue is related to Acrobat’s rendering behavior, not the PDF export itself.
How to fix or work around it
Option 1: Use a different PDF viewer (recommended)
Open the PDF in another viewer (for example, your browser’s built-in PDF viewer). In most cases, the table borders will appear correctly.
Option 2: Apply a white background to default table rows
If you need a workaround inside Wrepit:
-
Go to Workspace Settings
-
Open Tables
-
Select Default
-
Set the background color to #ffffff (white)
Important
Changing the default table background affects all tables in your workspace.
For example:
-
Tables placed inside grids with background colors will no longer inherit the grid background.
-
They will instead use the white background you defined.
Make sure this change fits your overall design before applying it, you can also use table settings on the specific tables in colored grids to override the white background color. This can reduce the visual rendering issue in Acrobat.
