ui: fix undefined table stats

Previously, if no value was being passed as totalCount,
the table stats were showing an "undefined value". This
commit as a default value as 0 for the total.

Fixes #89869

Release note (bug fix): show correct value on table
stats on UI, when there is no values to show.
