As advertised, this plugin is great for a non-techy admin to create and edit data, and I recommended the plugin for this purpose.
I used phpMyAdmin to setup the table and then used the plugin to create the initial set of records. There are no display facilities with the plugin so I a used a bit of custom code. Only 2 lines are needed to fetch the data into a php function:
$results = $wpdb->get_results( 'SELECT * FROM wp_mytable', ARRAY_N );
The plugin will allow access to only one table at a time, but its easy to switch between tables.
Thanks for sharing.
