Width columns category default template

Hello,

I still can't find a 'table class option'. I see that in category.less adminlist and bootstrap. Do you mean this? However, I don't know how to change it exactly. I'm afraid I will ruin the template when I don't know exactly what to change.
I would like to add some space in each column, so that the columns are not so small. The table has to be responsive.
Can you help me a little more with this?

hello
1 install beta 4 via github
2 assign table template to your category
3 go to template part => edit table template option
4 go to display parameters tab
5 in basic table you have a table class option
6 add a class like table table-stripped for exemple
save that it

Hello,

Thank you for your answer. I understand the steps you've described.
However, I'm still getting the error I previously described:

Problem solved. The fields in the table were not selected anymore. I selected them and now it is solved.
Thanks a lot!

with pleasure
