I asked the same to the MATLAB Central AI Chat Playground and it said the following -

To make the first row editable and all other rows non-editable in a MATLAB table, you can use the uitable function along with the CellEditCallback property. Here's an example:

% Create a sample table
data = {'John', 25, 'USA'; 'Emily', 30, 'UK'; 'Michael', 35, 'Australia'};
columnNames = {'Name', 'Age', 'Country'};
table = uitable('Data', data, 'ColumnName', columnNames);
% Set the CellEditCallback property
set(table, 'CellEditCallback', @(src, event) editCallback(src, event));
% Callback function to handle cell editing
function editCallback(src, event)
    % Get the row and column indices of the edited cell
    row = event.Indices(1);
    col = event.Indices(2);
    % Allow editing only for the first row
    if row == 1
        % Allow editing
        src.Data{row, col} = event.NewData;
    else
        % Revert to the previous value
        src.Data{row, col} = event.PreviousData;
    end
end

That seems like a potentially viable workaround.

Of course, since the default for uitable is that no columns are editable, you'd have to change that for the CellEditCallback to have any effect, e.g.:

% Set the ColumnEditable and CellEditCallback properties
set(table, ...
    'ColumnEditable', true, ...
    'CellEditCallback', @(src, event) editCallback(src, event));
