Affects Versions: 1.12.0
Reporter: Xinli Shang
Assignee: Xinli Shang
Fix For: 1.12.0
To determine which column to be removed when running the 'prune' command, one
of the factors is to check the size of each column. This Jira is to add a
command to get the size in both bytes and the percentage of each column. It can
be considered as the width of each column.
