Vertcat tables with structure variables with different fieldnames

Hello! I'm having troubles when creating a table within a loop because some table variables are structure arrays that have different fieldnames. I get the following error :

Error using vertcat : Names of fields in structure arrays being concatenated do not match. Concatenation of structure arrays requires that these arrays have the same set of fields.

Example of my code :

%Inputs
ExampleTable = table();
Orig_1 = struct('m4ADG','folder_1','Group','folder_group');
Orig_2 = struct('m5B0','folder_2','Group','folder_group');
item = {'charArray',[1 1 1], Orig_1; 'otherChar',[1 2 1], Orig_2};
%function
VarNames = {'Var1','Var2','Var3'};
for j = 1:size(item,1)
    Var{1,1} = item{j,1};
    Var{1,2} = item{j,2};
    Var{1,3} = item{j,3};


NewTable = cell2table(Var);
NewTable.Properties.VariableNames = VarNames;

if isempty(ExampleTable)
    ExampleTable = NewTable;
else
    tmp = table2cell(NewTable);
    ExampleTable = [ExampleTable; tmp];
end
clear NewTable Var
end

Error using tabular/vertcat (line 218)
An error occurred when concatenating the table variable 'Var3' using vertcat.

Caused by:
Error using vertcat
Names of fields in structure arrays being concatenated do not match. Concatenation of structure arrays requires that these arrays have the same set of fields.

This whole thing runs within a class with the defined property ExampleTable as table and item, Orig_1|2 comes from elsewhere. Do you know how I can fix the problem?

Use

    Var{1,3} = item(j,3);

so that the third variable is a cell containing structures, instead of trying to concatenate structures directly.

Thanks! it works! I also ended up transforming the cell into a table after the loop because cell2table would revert the cell-structure into a structure
