Right now the end of ksck's report looks like this:
So we have one summary line for each table as they are printed out and then at the end we say how many tables are bad. We could rework the last line like a table with information like this:
|some_table_name||1 under-replicated tablet|
Maybe we could also give the detail of how many tablets are good, how many are missing some replicas, and how many lost a majority of their tablets.
