Column width

The more you work with table press the more questions come up.
As I mentioned in another thread I have many tables on my site. Most of them will have the same dimensions, hence I’ve set the following custom CSS:

.tablepress .column-1 {
	width: 100px;
}

.tablepress .column-2 {
	width: 100px;
}

.tablepress .column-3 {
	width: 150px;
}

.tablepress .column-4 {
	width: 100px;
}

.tablepress .column-5 {
	width: 75px;
}

From the beginning I thought I would only use table press to create actual tables with number and text. Since I’m not very good at html nor CSS I started to use table press to align 3-4 images in the middle of the page. (for some reason my theme don’t do that automatically)

My question is now, can I overrule my previous css-code for any specific table?

I’ve tried:

.tablepress-id-7 .column-1 .column-2 .column-3 .column-4 {
	width: 150px;
}

But that didn’t seem to have any effect…

The reason I see the problem is that one of the images becomes much larger than the other once… and I would prefer to make each image a bit larger.

Thanks in advance
