I have two dimensional data, as shown in figure.
I need to separate same first coloumn (column 1) data values and its corresponding second column (column 2) value, into groups.
How can I do this ?
Thanks in advance.

When you say "separated", what specifically do you mean? How do you want the output organized?
Do you still need just one table, but with the values sorted? Or one table, but with an additional variable to define the unique values in column1? Or maybe you need a new table for every value in the first column?

Another method using groupsummary
% Create demo table
g = repelem((1:2:9)',randi(4,5,1)+1,1);
T = table(g, rand(numel(g),1).*randi([2,8],numel(g),1), ...
'VariableNames', {'column1','column2'})
% Average column 2 for each group in column 1
Tstats = groupsummary(T,'column1','mean','column2')
