Problems:

• When zooming in/out, browser draw borders based on calculation (1px * [zoom]). So for example 1px * 150% = 1.5px and sometimes there is 1px border with and sometime 2px.
• Table is poorly designed using transparent backgrounds, which cause display problems.

Solution:

• Redesigned table (removed current pattern for displaying borders) and adding new solution
• Added 0.01px workaround, where browsers will fallback to at least 1px
• Changed the border-width to the appropriate decimal per scaling level at the end of the file
• Removed opacity for disable table row, because it affects background color and also text => added text color and background color from Stacks color palette

Results:

Zoom 100%

All tables looks similar - There are only small things caused by the fact that I remove the transparent border.

Zoom 150%

Tested

• Tested on Chrome 106.0.5249.91, Safari 15.6.1, Firefox 105.0.1, Edge 105.0.1343.53

Note

I created all variations of Table component in Figma, if designers would like to use it in their component library.

What do you think?

Hope it helps!
