Hi all,
I am trying to format a legend in ArcGIS Pro to look like a table. Essentially, all I need is to add lines between each item and between the items and their descriptions. This is a template for a map that will change frequently so I want the table to adjust size when the descriptions for the items change. If it was static I would simply draw the lines in.
This is the table I'm trying to approximately replicate:

This is as close as I have been able to get so far:

Any help would be appreciated.
Thanks!
