Greppable table output without TTY

[calebstewart]

I'm writing a command line interface, and would like the output with a TTY to be a rich table, but when piped to an external command, simply display a greppable output without headers. As an example, a table like:

Name	Description
thing	thing description
thing2	thing2 description
thing3	thing3 description

Would be displayed like a normal Rich table when stdout is a TTY, but would be written like this when the output is a "dumb" terminal or file (with a configurable separator ideally, but defaulting to something like a tab):

thing thing description
thing2 thing2 description
thing3 thing3 description

This could be accomplished manually in the application, but it seems like possibly a useful thing to wrap into the Table class (obviously optionally). A very brief idea for what this /could/ look like is below (although, I can't say I'm happy with that; it's just an off the cuff example):

from rich.table import Table
from rich.console import Console

console = Console()
table = Table("Name", "Description", dumb_fallback="greppable", greppable_separator="\t")
table.add_row("thing", "thing description")
table.add_row("thing2", "thing2 description")
table.add_row("thing3", "thing3 description")
console.print(table)

I'm not sure if this fits or is possible with all the other formatting used in Rich tables, so if this is out of scope, then that's totally fine. No worries. Just an idea. I absolutely adore this library regardless ❤️
