Use of TablePress

Both links you posted have sidebars. The width of the tables is set to 100% and occupy the width of the entire container. I don’t see the problem.

I had switched themes to Blackoot. I’ve switched back to Dark TT, now, so you can take a look.

Sorry I think I was looking at the wrong thing. I think the problem is with the width:

#primary, #secondary {
    float: right;
    overflow: auto;
    width: 220px;
}

I changed the width to auto it seemed to work.

#primary, #secondary {
width:auto;

}

see if that fixes the problem.
