    1. COperfect..can you explain the code. Also in a big table, can find() be slow? How about $('table td:nth-child(' + index + 1 + ')').hide() or should I use the approach you suggested?

    2. CO@user1089173 find will always be faster than using multiple nested selectors. One thing you can do to make it fast it to assign the same class to all the tr's. start up and just hide them with that selection. That will be much faster.

Guidance
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).
