How can I display data inside a table in expanded form?

Greetings... I have a simple strcuture array (s) of two fields: name and data. Assume the array length is two. I wanted to display it in a table form in the command window. So, I used {struct2table} and generated a table T and displayed it in the command window. The problem is that, the table displays the data column in a collapsed form. Assume that s(1).data and s(2).data are (1 x 7) double arrays. The table displays them in that collapsed form: [1x7 double]. I want to expand each one inside the table and show it detailed, like [1.2 3.6 ...] in its place in the table. How can this be done? Thanks in advance.

Well, Matlab is not a spreadsheet application; presentation is not it's strong suit.
Have you investigated the workspace variable viewer? It would show the elements of the field in the structure in a spreadsheet-like interface, but it can't place multiple variables on the same page such as what a table is able to consolidate.

If you are only using table to display, then what you should be using instead is sprintf() or sprintf() with formats that include widths (possibly calculated) and possibly negative widths if you want left alignment.
>> sprintf('%-10s', 'hello')
ans =
'hello '
>> sprintf('%10s', 'hello')
ans =
' hello'
In particular, suppose you have a cell array column vector Names and a double array Values with the same number of rows.
ncol = size(Values,2);
fmt = ['%-15s ', repmat('%15g ', 1, ncol-1), '%15g\n'];
data = [Names, mat2cell(Values)] .'; %transpose is important
fprintf(fmt, data{:});
