Text Filter
Text Filter accepts free text inputs from users.
Options
- Default Value: Optional. The filter defaults to this value if no filter value is set by the user.
- Help text: Optional. Description of the filter.

How to use
It is recommended that table's text field and the text filter are both wrapped in LOWER() function
[[ LOWER(U.realname) LIKE CONCAT('%', LOWER({{name}}), '%') ]]
AND [[ LOWER(U.email) LIKE CONCAT('%', LOWER({{email}}), '%') ]
