Table data not showing up in the production. (but works fine in the localhost)

[akhilvc10]

Table data is showing up exactly the way I wanted when I run it in the localhost (dev mode).
But when I try to run and serve the build files locally the react-table data ain't showing up , same result when I host the app as well.
I could see the table tags getting rendered but not the data inside it. Any idea why this is happening?
