how to change names of columns in a table in matlab

You can change the names of variables (columns) in a table in MATLAB by reassigning the VariableNames property of the table with a new set of names. Here's an example:

main.m
% Create a sample table
T = table([1;2;3], [4;5;6], [7;8;9], 'VariableNames', {'A', 'B', 'C'});

% Display the original table
T

% Change the variable names
T.Properties.VariableNames = {'X', 'Y', 'Z'};

% Display the updated table
T
234 chars
12 lines

In this example, the VariableNames property of the T table is assigned a new set of names ({'X', 'Y', 'Z'}) to update the names of the variables (columns) in the table.
