there is a style in light.css which you can change/remove/overwrite
.ia_tableComponent__selection {
background-color: rgba(12, 123, 179, 0.25);
}
if you dont know how to change the theme.css you can also inject this it into a styleclass’s background-image:
(no need to give the class to any tables btw it will work on all tables just by being in the styleclasses)
}
.ia_tableComponent__selection { background-color: unset; }{
