Extjs Pivot Grid Row Numbers

Question

In the kitchen sink classic pivot grid configuration plugin example there are row numbers in the first column of the grid. Does anyone know how to do this?

Here's the link to the example https://examples.sencha.com/extjs/7.1.0/examples/kitchensink/?classic#configurable-pivot-grid

I tried setting rowNumbers to true but it didn't work

Thanks

rownumberer is column type. you must use it in columns

columns: [
    {xtype: 'rownumberer'},
    {text: "Company", flex: 1, sortable: true, dataIndex: 'company'},
]

Edited:

sorry for wrong answer. it was for ordinary grid. to show rowNumbeber on pivot grid set

selModel: {
        type: 'spreadsheet'
    },
