How do I convert all data from structures & substructures in a cell into a table?

I have a cell vector, in which each entry is a structure. Some of the fields in a structure is also a structure. For example:

Data{1,1}.a=1;
Data{1,1}.b='b';
Data{1,1}.K.x='x';
Data{1,1}.K.y='y';
Data{1,1}.K.z='z';is

Data{2,1}.a=10;
Data{2,1}.K.x='x';
Data{2,1}.K.v='v';

I want to convert the fields and data from structure into a table. For example, I would like to see:

T =

a b x y z v

---------------------------------

1 'b' 'x' 'y' 'z' ''

10 '' '' 'x' '' '' 'v'

Please download the attached file 'heteroStruct2table.m' and see the following example:

Data{1,1}.a=1;
Data{1,1}.b='b';
Data{1,1}.K.x='x';
Data{1,1}.K.y='y';
Data{1,1}.K.z='z';

Data{2,1}.a=10;
Data{2,1}.K.x='x';
Data{2,1}.K.v='v';

T = heteroStruct2table(Data,'K')

What the "heteroStruct2table.m" file does is to

1. add the missing fields in the original structs to make it become homogeneous

2. convert a cell array of homogeneous structs to table
