Here is the script on how to color the Pivot cell based on the value of this cell.
For example color the cells that contains the value "True":
//Text column formatting
widget.on('ready', function(se, ev){
var evalCol = 12; //fidx val of column to evaluate
var formatCol = $('td.p-dim-member[fidx='+evalCol+']'); //jquery pull entire eval column into array
$.each(formatCol, function(a, b){ //function to loop through array
if(this.textContent == 'True'){ //evaluate text conent of each cell in column's array. note: need to use JavaScript this instead of JQuery $(this), since textContent is a JavaScript attribute.
$(this).css('background-color','#32CD32); //set conditional styling
}
});
});
