Overhead is 'wasted' space in the table. It happens if a table has variable length rows, and you delete one in the middle of the table. To fix it, OPTIMIZE the table occasionally.

Hi All, I am using phpMyAdmin to analyze my mysql tables in Linux. On some of the tables, I see "Overhead" marked in red. For example: Space usage : Type Usage Data 732 Bytes Index 1,024 Bytes Overhead 732 Bytes Effective 1,024 Bytes Total 1,756 Bytes Can anyone tell me what this means, and how I can fix it please?
