Question Changing "Last Post" Column Width

I have read this "Before you ask for help with template issues ...."

I have also read this and tried the fix - " linkTOPIC: How do I increase the width of the Last Post column? "


I put this

td.td-6 {
width: 45%;
}

I also tried

#kunena td.td-6 {
width: 45%;
}

into file ../components/com_kunena/template/default_ex/kunena.forum.css

As you can see below it does not work for me
Thanks in advance for your help

Figured it out

TO change the Last Post column width on Category Page

td.td-5 {
width: 45%;
}

Note: the information that I gave in How do I increase the width of the Last Post column? , although related toa non-standard Kunena template (jp-kunena_blueface-1-5-7), related to in the "Recent Discussion" view. This topic involves the Categories view
