Header vertical white lines

[loriangrey]

TanStack Table version

v8.21.3

Framework/Library version

React v19

Describe the bug and the steps to reproduce it

There are rendered vertical white lines inside the header. Mostly on the side of the header columns. Inspecting it with the dom inspect-tool I can't realize any borders or border-colors set on the header columns. This phenomen following me since multiple React Tanstack Table versions. After refreshing the page either it disappears or it still remains.
