headerTemplate

sets the function that fires for each columns' header and returns header text

Example

webix.ui({
    view:"pivot", 
    headerTemplate: function(config){
        // return string with header template
    }
});

The function fires for the bottommost header in case there are several header lines.

It must return a string with the header text.

The config parameter is an object with the following properties:

• text - (string) the text to display
• operation - (string) the name of the operation to display
• name - (string) the column's inner name
