This is similar to #6500 and #6501 : In my docs, the dark-theme is noted in the html-part as

html< ... data-theme=dark ... >

and xarray-tables look therefore awful with the dark theme, as they are not rendered properly, as can be seen, e.g., here: https://emsig.xyz/emg3d-gallery/gallery/tutorials/simulation.html#create-survey.

This can be fixed by extending

to

html[theme=dark],
html[data-theme=dark],
body[data-theme=dark],
body.vscode-dark {
