Example：

<Table>
    <Table.ScrollContainer>
      <Table.Content aria-label="Example table">
        <Table.Header>
          <Table.Column>Name</Table.Column>
          <Table.Column>Role</Table.Column>
        </Table.Header>
        <Table.Body isLoading={loading}>
          <Table.Spinner  />
          <Table.Row>
            <Table.Cell>Kate Moore</Table.Cell>
            <Table.Cell>CEO</Table.Cell>
          </Table.Row>
        </Table.Body>
      </Table.Content>
    </Table.ScrollContainer>
    <Table.Footer>{/* Optional footer content */}</Table.Footer>
  </Table>

Have you tried using renderEmptyState to render your loading spinner? It only shows when the body collection is empty.
