CSS not having any effect on column width

Hey Tobias,

First of all, thanks for this wonderful plug-in!

I’m having trouble with a table where the CSS I’m adding isn’t having any effect on my table.

I want the first column to be 300px wide, and every other column 50px wide. This is the CSS I’m using:

.tablepress-id-12 .column-1 {
	width: 300px;
	padding: 0;
}

.tablepress-id-12 .column-2,
.tablepress-id-12 .column-3,
.tablepress-id-12 .column-4,
.tablepress-id-12 .column-5,
.tablepress-id-12 .column-6,
.tablepress-id-12 .column-7,
.tablepress-id-12 .column-8,
.tablepress-id-12 .column-9,
.tablepress-id-12 .column-10,
.tablepress-id-12 .column-11,
.tablepress-id-12 .column-12,
.tablepress-id-12 .column-13,
.tablepress-id-12 .column-14,
.tablepress-id-12 .column-15,
.tablepress-id-12 .column-16,
.tablepress-id-12 .column-17,
.tablepress-id-12 .column-18,
.tablepress-id-12 .column-19,
.tablepress-id-12 .column-20,
.tablepress-id-12 .column-21,
.tablepress-id-12 .column-22,
.tablepress-id-12 .column-23,
.tablepress-id-12 .column-24 {
	padding: 0;
	width: 50px;
}

If you could please tell me what’s wrong that’d be great.

Cheers!
