Sometimes, I'll see columns that are very wide but are filled with very little text, so they're mostly just white space.
It may be nice to automatically adjust their widths depending on the content in their column.
Maybe this wouldn't work out well in practice, but it might be worth trying
We have this support, but it auto sizes all columns. We use this for console.table and SQL databases.
To match the OS, we should hook up double-click on the column resize to resize single columns to fit.
We could also hook up the existing auto size support to a context menu.
