How can I hide columns from fiter list ?

[rickyspires]

Hello.
How can I make undefined columns hidden from the filter list ? i.e the empty one in the image below.
Also is there a way to remove columns from the list that are hidden ?
Also can I remove the Edit / Delete columns ?

Thanks

/i have found a solution for one of my questions.

I can hide the first and last item in the dropdown list by doing return this.columns.slice(1, -1); on line 47 of bootstrap-table-filter.js

BootstrapTable.prototype.getColumns = function () {
    //remove first and last item from filter list.
    return this.columns.slice(1, -1);
};
