Introduce a compact layout for ncol=1

[prisae]

My proposition as an alternative to #82 @akaszynski - what do you think?

It does the following:

• If ncol=1, it left-aligns everything.
• It adds a new max-width parameter, with which the user can control the max-width of the table.
• I tried to include all the other little cleaning-up bits you put into Improve HTML formatting #82.

An example how this "compact" layout looks:

Looks way better @prisae, this is good to go provided CI passes post-merge with main.
