Get attribute of table selection

[Anonymous User]

I'm developping a widget based on the table widget in Experience Builder.

Basically, I added 2 buttons on top of the table, and I want to fire some actions on my selected rows (selected though the table, not by clicking on the map), by a click on those buttons.

My main action is to automatically change the value of one attribute of the selected row(s).

I can't figure out how to access these attributes. So far, I can get an Array with the selected items, but it doesn't contain the attributes values I need. Can someone help ? Thanks.

changeStatus = () => {
    const selectedArray = (this.table as any).grid.selectedItems.items;
    console.log(selectedArray)
}

<Button onClick={this.changeStatus} size="lg"  style={{
                position: 'absolute',
                backgroundColor: 'red',
                borderRadius: 6,
                right: 180,
                top: 48,
         }}>Refuse</Button>
