Query results columns are too wide for long column names

Steps to Reproduce:

1. Run a query against a table with long column names, but the values aren't really long.

Expected: The column width should be size more aligned with the column content, not the column name. If a column is too narrow for the entire column name to show, it can be truncated with a trailing "...".

Actual: Columns are sized to column name, taking too much horizonal space. See screen below.
