How to get multiple buttons in 2 different columns in ng2-smart-table Angular2

I want to show buttons in more than 1 column in ng2-smart table in angular 2?

Has any 1 achieved this?

AS of now i have:

@Component({
selector: 'button-view',
template: `
Order Details
`
})
export class ButtonViewComponent implements ViewCell, OnInit {
...
}

export class OrderIssueComponent implements OnInit {

source: LocalDataSource;
...

button: {
title: 'Order Details',
type: 'custom',
renderComponent: ButtonViewComponent,

},
}

I want to use another different button name, but i am getting same button in both columns


If i try like below, i get same 'Order details' button twice in both the columns

button: {
title: 'Order Details',
type: 'custom',
renderComponent: ButtonViewComponent,

},

button2: {
title: 'Service orders',
type: 'custom',
renderComponent: ButtonViewComponent,

},

I need to get 'Service Orders' button
