cell2table only using first cell array row

I have a cell array as such:

E = 
  4x1 cell array

    {1x4 cell} 
    {1x4 cell} 
    {1x4 cell} 
    {1x4 cell}

Where each 1x4 cell array consists of a char array.

E{1} = 
    {'Input'}    {'azimuth_1p'}    {'real'}    {'-inf to inf'}

However the following code

T = cell2table(E{1,:},'VariableNames',{'IO_Type', 'Name', 'Type', 'Range'});

Only gives me the following table:

      IO_Type         Name          Type         Range    
      _______    ______________    ______    _____________

      'Input'    'azimuth_1p'      'real'    '-inf to inf'

Why aren't I getting all 4 rows in my table?

Why aren't I getting all 4 rows in my table?

Matlab does exactly what you asked. As you've shown E is a 4 (rows) x 1 (column) cell array. E{1, :} is the content of the 1st row and all the columns. There's only one column, so E{1, :} is the same as E{1, 1} or E{1}. The content of E{1} is a 1 (row) x 4 (column) cell array, hence you only get one row out of cell2table.

Note that if E had more than one column, then cell2table(E{1, :}, ...)| would have been equivalent to:

cell2table(E{1, 1}, E{1, 2}, E{1, 3}, ... )

which would have most likely errored unless E{1, 2}, etc. contained valid options for cell2table.

To convert your cell array of cell arrays to a table. First concatenate all the rows so you have a 4x4 cell array, then call cell2table:

T = cell2table(vertcat(E{:}), 'VariableNames',{'IO_Type', 'Name', 'Type', 'Range'});

You may want to review how you construct E so it is a 4x4 cell array (of char arrays) instead of a 4x1 cell array of 1x4 cell arrays (of char arrays)
