Change table border

you can use pixel 10px but that would be a really wide border. Try using these styles

border:1px solid;
border-collapse:collapse;

The first makes a border 1 pixel wide and the second command create one line between each cell.

If you don’t use the second style each cell will have its own border.

it depends on where the tables are located. For example if they are all enclosed in the same class you would use code like this.

.myclass table, caption, tbody, tfoot, thead, tr, th, td { border:1px solid [color]; border-collaspse}

are there any classes common to all the tables ?
