I cannot find any basic example of cellselectioncallback in the documentation. I know that the indices represent rows and columns, but I don't know how to implement it.

I am trying to achieve something like this:

When cell in row 1, column 1 is selected, then

Editfield.Value = 10;

When cell in 2, column 1 is selected, then

Editfield.Value = 22;

etc etc. And you shouldn't be able to select more than 1 cell at a time.

CellSelectionCallback documentation

Example in the documentation

The solution to your goal will look something like this where uit is the handle to your uitable.

uit.CellSelectionCallback = @cellSelectionCallbackFcn;
function cellSelectionCallbackFcn(tblHandle, event)
    switch event.Indices(1)  %  row number of selected cell
        case 1
            val = 10; 
        case 2
            val = 22; 
        otherwise           % optional
            val = NaN; 
    end
    Editfield.Value = val; 
end

Or, using indexing,

function cellSelectionCallbackFcn(tblHandle, event)
    vals = [10, 22];
    assert(numel(vals) <= event.Indices(1), '"vals" is undefined for this row.')
    Editfield.Value = vals(event.Indices(1)); 
end
