The table width is actually 100% of the space denoted by the tag #content.
Therefore, it is dictated by this (/osta/css/staff-desktop.css, line 55):
#content {
max-width: 1200px;
}
But #content is a global template element that affects all pages, so if you want to tinker with the ticket list table you’ll want to do something like this to /osta/user-styles.css:
.index-page #content,
.tickets-page #content {
max-width: 100%;
}
What you’ll find, however, is that this is not the magic fix that you are hoping for. The table itself will be wider, but the columns will retain their previous width. And if I remember correctly, setting the column widths using the new osTicket method of doing so is ignored by osTicket Awesome. But I could be wrong about this.
It has been a few months since I’ve tweaked the table layout, but let me assure you that possibly a hundred hours has gone into tweaking it over the past few years. I’m sure widening the table looks like a super easy thing to do, but even going from 940px to 1200px was a challenge.
Also keep in mind that if you make the table and columns wider, you’ll also want to test everything on smaller screens before declaring victory.
Please don’t mistake my willingness to point you in the right direction as a promise that you’ll find success, or a guarantee that I’ll support you in this endeavor.
Having said that, if you manage to pull off something that you are happy with and want to have it considered for inclusion in a future release, feel free to post your findings here.
