Add the created column to the end of the table and scroll to it

[romeovs]

Product doc

Currently, when creating new columns through the Extract/Combine column drillthroughs, or through the Extract/Combine column shortcuts in viz mode, the column gets added inconsistently:

• the shortcuts add the column to the end
• the extract drillthrough adds the column after the column it's extracted from, while the combine column drillthrough adds the column to the end.

Goals

• Make this more consistent by adding the new column at the end always.
• Scroll to the newly added column
