So, I got it to work, sort of …
.tablepress-id-1 .column-1 {
width: 250px;
}
.tablepress-id-1 .column-2 {
width: 200px;
}
I can’t seem to get the cell to go exactly as wide as I indicate. I tried exaggerating to 600px and it won’t do it.
As for the email link. I put code in the cell and that works, but the link is not aligned to the other text. Maybe it will work better if I use the link.
