I don’t get why the tbody th width should be set to calc(100% - 12rem).

tbody th {
  width: calc(100% - 12rem);
}

I haven’t understood the reason behind this specific width. If the width is not set it seems to work just the same. (And why 12rem?)

Thanks in advance.

Ya, it does seem like this might not be necessary since the three tds are each set to a width of 4rem and the th appears to automatically take up the rest of the space by default. But I haven’t tested it completely so I could be wrong and it may need to be there for a very specific reason.

Because you want it to take up all the remaining available space. So if the three tds take up 4rem each then that is a total of 12rem and thus the th should take up 100% of the space minus the 12rems that the three tds occupy.

Thanks a lot. I had not paid attention to the tds width.
