What youre looking for inside phpMyAdmin is at the very bottom of the database list.
1) select the tables you want to repair
2) use the drop-down menu at the bottom to select "Repair table" (see attached image posted below)
then read the results on the next page. if all goes well, you'll get a positive confirmation message.
