filter box

How can I do not equal in the filter box?
I tried these
{name:“name”, type:“text”, value:" != ‘Tom’ “}
{name:“name”, type:“text”, value:” !‘Tom’ “}
{name:“name”, type:“text”, value:” !=Tom “}
{name:“name”, type:“text”, value:” <> ‘Tom’ "},
yet they never work.
Thanks!

This math operator will be included in the next version of the Pivot. For now, you can use only the following operations: = >= > <= <

Alright thanks. Look forward to the next version then : )
