No more help needed! I basically extracted the data inside the categorical cell array and the double cell arrays with the code below.
[mycellarray{:}]
I thereafter created three different columns (new variables) and then created a new table from the three columns and saved it into a csv file :D
column1 = [table.Var1{:}];
column2 = [table.Var2{:}];
column3 = [table.Var3{:}];
table_final = table(column1, column2, column3);
writetable(table_final,'filename.csv','writevariablenames',0); % writing the table without headers of the variable names
