I'd personally have written "on other tables" or "on another table",
or left out that clause altogether and just said "concurrent
<command>VACUUM</command>".  I'm not sure it's ungrammatical exactly,
but the antecedent of "a table" is a bit unclear; people might
wonder if it means the table being reindexed.
