Not sure what you mean. A console is a type of table.
Cut the table in half! Cut the table to give you the width you desire. Fix to the wall with a batten. If you want two matching tables, cut out the centre of the table! If you want a narrower table with four legs, cut out the middle and fit the two ends together with metal repair straps underneath so cannot be seen. Smooth the joint and if necessary fill and re-finish. Hope that's of some help!
can you post a picture of the table please?
A shallow hallway style console table?
