The MySQL Table Editor is a component that enables the creation and modification of tables. You can add or modify a table's columns or indexes, change the engine, add foreign keys, or alter the table's name.
The MySQL Table Editor can be accessed in several ways, and most commonly by right-clicking on a table name within the Object Viewer and choosing ALTER TABLE. This will open a new tab within the main SQL Editor window. You can also access the MySQL Table Editor from an EER Diagram by double-clicking a table object.
