filtering syntax documentation

[letianzj]

Is there a documentation for data-table filtering. For example, how to filter rows containing (or not containing) a substring? Thanks.

So far I found from dash user guide are
-- Enter eq "Asia" in the "continent" column
-- Enter > num(5000) in the "gdpPercap" column
-- Enter < num(80) in the lifeExp column

@letianzj Thanks for the question. The feature is being reworked in depth and part of that work will include better documentation for filtering. You can follow the progress in this PR

There's currently no syntax for contains but it is something we want to add sooner than later.
Cross-linking with #169 for reference.
