What is the central columns feature in Phpmyadmin?

Answer 1

Central columns is a phpMyAdmin feature that makes it easy to copy a column definition to another table. This can be useful when defining tables linked by a foreign key. It's available only in phpMyAdmin 4.3 and later and it requires configuration storage to have been setup.

To add a column to central list, go to table structure page, check the columns you want to include and then simply click on “Add to central columns”. If you want to add all unique columns from more than one table from a database then go to database structure page, check the tables you want to include and then select “Add columns to central list”.
