What is the best way of deleting multiple rows of a uitable using a pushbutton?

I am creating a to-do list where entries, dates, identification of importance are each column in a uitable. I want to delete one or more rows depending on what the user selects or identifies with a delete button that is also in the GUI.

Use the same kind of vector of handles that we discussed in https://www.mathworks.com/matlabcentral/answers/334500-how-to-sort-string-in-a-list-of-edit-box-based-on-a-toggle-buttons-for-each-of-them#answer_262392

When you have converted the vector of checkbox values from cell to matrix, then you can logical() that to get a mask. The mask would correspond to entries to delete. For your purpose it is probably easier to use a vector of things to save:

   mask = logical(MatrixCheckboxesValue);
   IndexC = ~mask;

Then this next section is copied directly from that previous code:

   ReorderCheckboxes = CheckboxesVValue(IndexC);
   ReorderEntryEdits = EntryEditsVString(IndexC);
   ReorderDueDateEdits = DueDateEditsVString(IndexC);
   ReorderImportantToggles = ImportantTogglesVValue(IndexC);

but only a subset of the locations are to be changed:

   num_kept = sum(IndexC);

   set( DueDateEditsV(1:num_kept), {'String'}, ReorderDueDateEdits);
   set( EntryEditsV(1:num_kept), {'String'}, ReorderEntryEdits);
   set( CheckboxesV(1:num_kept), {'Value'}, ReorderCheckboxes);
   set( ImportantTogglesV(1:num_kept), {'Value'}, ReorderImportantToggles);

After that, you have some unused entries to deal with, the ones from num_kept+1:end . You could delete them, or you could set their visible off and put them in a pool of already-created objects ready for re-use.
