[REQUEST] Add title_justify and caption_justify options for Table, to override default "center"

[ptmcg]

How would you improve Rich?

I would like to output a table with the caption non-centered, as shown here:

                 Best 5 Star Trek:TOS Episodes

                                               data from IMDB.com

What problem does it solved for you?

Sometimes captions should be less prominent than showing as centered under the table. Left or right alignment of the caption text can give it more of "footnote" look.

While supporting caption justification, may as well add title justification also.

See attached patch for proposed code changes.

You can set the caption to a Text instance, i.e. caption=Text("data from IMDB.com", justify="right") which should have the same effect.

That said, it probably is worth adding those two parameters as you suggest. Just to make it obvious...
