Headers

[Alexsandr Litkevich]

Hi why can't the package read headers?
const headers = [ { label: 'First Name', key: 'firstName' }, { label: 'Last Name', key: 'lastName' }, { label: 'Email', key: 'email' }, { label: 'Address', key: 'address' }, { label: 'Postcode', key: 'postcode' }, ];
I get this instead of headers.

"[object Object]","[object Object]","[object Object]","[object Object]","[object Object]"
