I have seen that simple invoices is using a component (ricoLiveGrid) to get the lists sortable. In this lists the even rows is painted with one color and the odd rows in another color.
In the invoices list I have a column where I print "yes" or "no", depending if the invoice has been paid or not. Now I want to print the rows of the paid invoices with another color, but I can´t find the way, as the ricoLiveGrid aplies a kind of "facade" in front of the html written in /invoices/manage.tpl.
check out the css files in : ./modules/include/js/lgplus/css/
if you want the row to be another colour you'll have to add a specific css class to that row and then edit the css files to add something ie, .pepRowBg { background-color:#dcdcdc; }
best option is to use firebug in firefoc and mess aournd with the css until you get it right
also note: in the next release (1-2 months) we've removed ricoLiveGrid and started using extjs.org's grid
