MUI-Datatable: TableHead inside Expandable Row keeps on repeating for every row of the table and table does not center

How do I solve this? Table headings just keep on repeating for every row in the table as seen in the picture below. Also, the table is always at the far end of the right side. How can I make this at the center as well?

    responsive: "simple",
    expandableRows: true,
    renderExpandableRow: (rowData, rowMeta) => {
      console.log(rowData, "rowData");
      return Object.entries(rowData[3]).map(([key, value]) => {
        return (
          <TableContainer>
            <Table>
              <TableHead>
                <TableCell align="right">Name</TableCell>

                <TableRow key={key}>
                  <TableCell component="th" scope="row">
                    {value.name}
                  </TableCell>

                  <TableCell align="right">{value.color}</TableCell>

                  {/* Product: {value.name} + {value.size} +{" "}
                  {value.color + value.quantity} */}
                </TableRow>
              </TableBody>
            </Table>
          </TableContainer>
        );
      });
    }
  };
