column width

Hi,
I read the forum, tried a lot of things but nothing resolves my problem. Which is strange because it should be a simple thing…
With
.tablepress-id-8 .column-1 {
width: 50px;
}
I can change the column with in table in https://www.tejedatravel.com/individuele-rondreis/andalusie/fly-drive-15-dagen/

With
.tablepress-id-40 .column-1 {
width: 50px;
}
nothing happens in https://www.tejedatravel.com/fietsen-in-andalusie-op-via-verde/
I would be really greatful if you could have a look at this..
