Remove table-striped option for Category List

I am trying to tweak the coloring of the site and making it look to my own desire, On the category’s list it doesnt look nice at all. 
The table shows white grey white grey, as can be seen here:

There is an element when I inspect the code, but I don’t know where to find the file to modify to remove the table-striped element. 
The full line of code with this in it is <table class=”category table table-striped table-bordered table-hover table-noheader”>
I have the LT Design theme 
 
Any help would be appreciated
