CX Zoom AWB/ Task 2
Description	Implementing behavior change for {{PresFoot}}, compliance with MOS:CHRONO
BRFA	Wikipedia:Bots/Requests for approval/CX Zoom AWB 2
Status	In BRFA
Frequency	Non-recurring
Type	AWB, Python, Manual

Background

{{PresFoot}} currently accepts parameters for the last row, as well as closes the table. This behaviour is undesirable. Hence, {{PresFoot}} is to be converted to a pure table closer, and the last row being replaced by the standard {{PresRow}} template.

Process

If {{PresFoot}} is present, change all existing cases of PresFoot(with parameters) to PresRow(with parameters). (2950 cases)
Add {{PresFoot}} with no parameters to a new line after final {{PresRow}}. (same articles)
While doing these changes it makes sense to bring these tables' usage into compliance with WP:CHRONO (earliest to latest).
Remove stray table close in articles that have a PresFoot followed by an unnecessary stray table closer.
