    The problem here is very similar to your old question with my answer https://tex.stackexchange.com/a/485086/16550 Where do you have the command \tablesize from? It is undefined, in this and your last question of tables I already mentioned it ... – Mensch Apr 17 '19 at 07:50

You get

! Undefined control sequence.
l.13 \tablesize
               {\small}

just use \small

Then you get the error

! Undefined control sequence.
<recently read> \multirow

so add the multirow package.

Then you get no error (but is still too wide even at \small)
