## Filters

Filters are screens that you can set on your DataTable to limit the quantity of samples you wish to work with. Filters are very often used in restricting the sheer amount of information available to make data tables and graphs more substantial to people.
The following options exist to work with Filters in the DataTable:

- Add Filter... - Adds a Filter to the DataTable.
- Remove Filter... - Removes a Filter from the DataTable.
