How can I Ensure Transparency in parfor-Loops when using cell2table ?

I am using parfor which contains a for loop and in it I have:
ranked_global_firstorder=sortrows(empty_cell_fo,[2],'descend');
ranked_global_firstorder=cell2table(ranked_global_firstorder);
ranked_global_firstorder.Properties.VariableNames=["m","ranked_global_first_order"];
descending_per_Ns_fo(:,k-1)=[table(m);ranked_global_firstorder(:,1)];
I am getting the following error:
Error using cell2table (line 39)
Transparency violation error.
See Ensure Transparency in parfor-Loops or spmd Statements.
If anyone can offer any insight into how I can solve this, I would be very grateful. I am new to parfor and while I did read certain stackexchange pages, I cannot figure it out. Thank you very much in advance. Cheers.

Which MATLAB version are you using? What is the name of the file you stored this code in? And please check whether the cell you are passing in is possibly empty.

Most of the table-building functions can have this problem if you do not specify 'VariableNames', like this (tested in R2019a):
parfor i = 1
c = {1, "foo";
2, "bar";
3, "baz"};
t{i} = cell2table(c, 'VariableNames', {'numbers', 'words'});
end
disp(t{1})
