How can I sort the terms in a URL (inner table)?

Depending on how you want to sort:

 
• Clicking an inner table's column title will sort the term rows by it.

• Clicking "Columns & Sorting" button above the data tables -> "Terms order by".

You can also set a default sorting order in the "PRT Settings" (top right under the settings icon). Columns & Sorting -> Default Terms order by
