PHP 7 Compatibility

Hi! I did a PHP 7 compatibility scan on a website and the Tablepress plugin is causing the following error:

FILE: /nas/content/live/nceesorg/wp-content/plugins/tablepress/views/view-about.php
————————————————————————————————————
FOUND 2 ERRORS AFFECTING 2 LINES

187 | ERROR | Extension ‘mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0; Use mysqli instead

Could you please fix this? Thanks!
