Row Unique Id for MaterialTable v4

[ofirTelecareBill]

I'm using MaterialTable v4, and I'm trying to get rid of a warning:

The table requires all rows to have an unique id property. A row was provided without id in the rows prop. To prevent the loss of state between renders, please provide an unique id for each row.

I tried adding this:

components={{
       Row: props => <MTableBodyRow id="SOME-ROW-ID-HERE" {...props} />
}}

But it's complaining about MTableBodyRow:

Line 1000:40: 'MTableBodyRow' is not defined react/jsx-no-undef

Any thoughts on this?
