MaterialTable.detailPanel should work via func and object (aka { render: foo })

I was getting this issue after upgrading to 2.3.7 when I built my code for production and it was live, but running locally not it ran just fine did not show any errors.

const details = (rowData) => {
     <span>bob</span>
}
<MaterialTable
        columns={columns}
        data={data}
        title=""
        detailPanel={details}
        options={options}
        onRowClick={(event, rowData, togglePanel) => {
          togglePanel(rowData.tableData.id);
        }}
      />

Once I added the render in the detailPanel it worked just fine before build and after. Would be nice to throw a error if you are forgetting to pass in render. Code after looked like this:

<MaterialTable
        columns={columns}
        data={data}
        title=""
        detailPanel={[{ render: details }]}
        options={options}
        onRowClick={(event, rowData, togglePanel) => {
          togglePanel(rowData.tableData.id);
        }}
      />

Looks to be resolved in 2.3.7
