Unique function counts null and empty values

[Mart124]

Hi,

Describe the bug Doc states the following : https://tabulator.info/docs/6.3/column-calcs : The unique function counts the number of unique non-empty values in a column (cells that do not have a value of null, undefined or ""). But unique does count null and "" values.

Tabulator Info Reproduced with Tabulator 6.2.5 and 6.3.0.

Working Example https://jsfiddle.net/wb35eqx0/

Expected behavior Unique does not count null and "" values, and a a result, last 2 columns of the working example above should have their count to 0.

Desktop (please complete the following information): Tested with Safari, Chrome, Firefox.

Thank you very much 👍
