Tab is divided into 4 major collapsible sections (Columns, Constraints, Indexes and Triggers) and bottom panel for selected item details. Here is explanation of changes highlight annotation on the above screenshot:

1 Changed item (`phone` which has changed Nullability)
2 New item (`address2`)
3 Unchanged column with changed column order (`district`)
4 Changed column with changed column order (`location` has changed nullability)

Vertical toolbar between two panels contains additional tab-specific actions:

Open data diff for the current table
Open data diff for the current table filtered only to new and changed records
opens query result diff with select top 1000 records statement for this table
'Open table definition as text' opens text diff tab with table script generated by application
'Open SHOW CREATE TABLE result' opens text diff tab with table script provided by database server with SHOW CREATE TABLE command

Please note that merge/delete action may fail because of limitations caused by other objects such as foreign keys, existing data and so on. Please check the merge execution result for details.

Column Extra for columns can have one of the following items: AUTO_INCREMENT, ON UPDATE rule, VIRTUAL GENERATED, STORED GENERATED or INVISIBLE. The last one (INVISIBLE) can be combined with others. If the column is AUTO_INCREMENT and selected to be merged, then the generated merge statement has PRIMARY KEY included even if it is not selected in Constraints, because auto-increment can not be specified without a key. VIRTUAL GENERATED and STORED GENERATED correspond to generated columns, and in this case column Generated As also includes column generation expression.
