I believe the answer is:
trestle
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">supporting framework</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for trestle that I've seen before include "Framework for holding a tabletop" , "Supporting tower" , "horse" , "Framework to hold table top" , "Letters (anag) - table" .)
