No, maybe I think of the “MB Custom Table” in a wrong way.
What I want is to allow my client to edit the posts while they are in the wp admin section, and looking at the admin post list.
Something like the plugin “wp admin columns” does.
So instead of entering into each post to make changes, they could do that in a table view on the admin side.
That way they can make quick changes to field I define, but in “excel” view…
