Current Caddy code used a combination of CSS styles that
some mainstream browsers (e.g. Firefox) do not support well:
"td:first-child { width: 100%; }" together with
"td:last-child { padding-right: 5%; }".

The old approach was three columns with:
- "Name": 100% width, 5% padding left
- "Size": minimal width
- "Modified": minimal width, 5% padding right

Now the new approach is five columns with:
- <Dummy>: 5% width
- "Name": 80% width
- "Size": minimal width
- "Modified": minimal width
- <Dummy>: 5% width
