Hello, I already programed an "add row" button but I don't know how to program a "delete row " button.I tried to copy the same function and add a - instead of a + but it does not work. I'll attach the captures with the code, including the FCN start up callback. Thank you

Hey,

idx = app.UITable.Selection(1); 
app.UITable.Data(idx, :) = [];

Selection varies whether you have MultiSelect on or off. Check this document if you have MultiSelect on https://www.mathworks.com/help/matlab/ref/matlab.ui.control.table-properties.html#d124e1617327

Below is Walter's comment from the comment section.

%inside callback
fila = app.UITable.Selection;
if isempty(app.UITable.Data) || isempty(fila); return; end   %table is empty or nothing is selected
app.UITable.Data(fila(1),:) = [];  %delete what is selected
