How to perform different operations on the same column in the pivotgrid?

[officecode]

For example, I want to perform both max and min operations on the price column, but the results are all max.

Code:

pivot:{
	rows: ...,
	columns: ...,
	values:[
		{field:'price',title:'price_max',op:'max'},
		{field:'price',title:'price_min',op:'min'}
	],
},

Also, how can I get the forzenColumn column in the pivotgrid? I want to modify the width of it.
Thank you.

You can't do that. The field in the columns must be unique.
