colortbl
doesn't much like \extracolsep
. For individual cells you can fiddle with the optional overhang arguments, but for rows that's a bit difficult.
Also your table isn't full width as the \extracolsep
glue is balanced by \LTleft
and \LTright
glue that is either side of the table.
If you make it full width, making the colour bands is much easier, as you know in advance how big they need to be:
