Hi everyone,
I've multiple tables imported from excel where they are organized one for sheet. They include observation for countries at different times (sheet1=1-st year, sheet2 = 2-nd year,...). I'm trying to reorder them by their table labels (country name).
Can you help me? Thanks.

Here is how to use sortrows() to reorder a table by the country names column:
% Sort table alphanumerically by the first column (the table with the country rows in it).
t = sortrows(t, 1)
Here is a full demo, which includes creating some data and then sorting it:
% No data was included in the question, so we are forced to create some on our own.
for row = 1 : 15
countries{row} = sprintf('Country %02d', randi(99, 1, 1));
data(row) = rand(1);
end
% Make a table from these two row vectors. Use (:) to turn them into column vectors, then use table().
t = table(countries(:), data(:), 'VariableNames', {'Country', 'Data'})
% Now we have the sample data with country names in random order, and we can begin.
% Sort table alphanumerically by the first column (the table with the country rows in it).
t = sortrows(t, 1)

Well, unless you can upload these multiple tables, or workbook with multiple sheets in it (ideally with code to read in all the sheets), you're making a lot harder for me. I think I'll just wait for the data, along with what you want as the output.

Thanks, I think that I've solved my problem.
for c=1:width(CDS_1Y)
SpreadCurves{:,c}=[CDS_1Y(t,c);CDS_2Y(t,c);CDS_3Y(t,c);CDS_4Y(t,c);CDS_5Y(t,c);CDS_7Y(t,c);CDS_10Y(t,c);CDS_20Y(t,c);CDS_30Y(t,c)];
end
% "c" is the label (country) founder "t" is another parameter. "CDS_*" are originally tables names.
%% With this code you can pick the column for the same label from multiple tables and recombine these in a table for any label.
