As the summary says; when I want to click an individual cell in an uitable, i want it to change properties. For example, when I click a certain cell, I want the cell to change its foreground color permanently. I hope it's not too hard to do. Thank you in advance.

Hi @Constantin Vlad Mihai,

I understand that you wish to change the 'ForegroundColor' of the particular cell of the 'uitable' when the cell is clicked by the user. As I understand the 'ForegroundColor' of the 'uitable' changes the color of the text present inside the cells of the 'uitable'.

This can be done in the following ways:

Add a 'CellSelection' callback to the 'uitable' component.
Inside the 'CellSelection', create a 'uistyle' object with the required styling.
Use the 'addstyle' function to add the 'uistyle' created to the particular cell.

Here is an example:

function UITableCellSelection(app, event)
    if ~isempty(event.Indices)
        row = event.Indices(1);
        col = event.Indices(2);
        
        % Create a style object
        style = uistyle('FontColor', 'red');
        
        % Add the style to the selected cell
        addStyle(app.UITable, style, 'cell', [row, col]);
    end         
end
