    1. COAs for problem 1, I just wanted to hide that column not actually completely remove it from the Model, which is what that code should be doing (according to Java Docs). as for 2, not sure why that really applies. As for 3 thanks for pointing that out it appears to process a little fast. The do not apply as all that JFrame code was just to get a runnable code section for you all to look at.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
