add new columns with different siyes to a table in matlab

To add a new column with different sizes to a table in MATLAB, you can follow these steps:

1. Define the new column vector with the desired size.
2. Add the new column to the table using the addvars function.

Here is an example code snippet:

main.m
% Define a table
T = table([1; 2; 3], {'A'; 'B'; 'C'}, 'VariableNames', {'ID', 'Name'});

% Define the new column vector with different sizes
newCol = ['X'; 'Y'];  % size is 2x1

% Add the new column to the table
T = addvars(T, newCol, 'After', 'Name', 'NewVariableNames', 'NewCol');

In this example, we define a new column vector with size 2x1 and add it to the T table using the addvars function. The 'After', 'Name' argument specifies that the new column should be added after the Name column, and the 'NewVariableNames', 'NewCol' argument specifies that the name of the new column should be NewCol.

Note that the size of the new column vector should match the number of rows in the table. If the new column vector has a different size than the table, an error will occur.
