How to delete selected rows in uitable?

Question

I'd like to delete selected rows of an uitable. I thought about using a checkbox for every row to select which one I want to delete.

But I can not add a column to a table with checkbox Set to false.

I get this follow error

??? Conversion to cell from logical is not possible.

Error in ==> loadTable at 7
    data(:,5) = true;

I tried with this:

 function loadTable(hTable, arrayHeaderAndData, columnFormatAtt)

        header = arrayHeaderAndData{1};
        % Add column delete
        header = [header 'Del'];
        data = arrayHeaderAndData{2};
        data(:,5) = true;
        columnFormatCases = [columnFormatCases 'logical'];

        set(hTable, 'Data',data,...
            'visible','on',...
            'ColumnWidth','auto',...
            'ColumnName',header,...
            'ColumnEditable', [false false false false],...
            'ColumnFormat', columnFormatAtt
    );


    end

Then I need to delete all rows with selected checkboxes from table. How can I do that?

Answer 1

There is no need for another column with checkbox, just to indicate which row you want to delete. I would rather use the uipushtool to add a delete button, which deletes all rows previously selected.

function myTable 

h = figure('Position',[600 400 402 100],'numbertitle','off','MenuBar','none');

defaultData = rand(5,2);
uitable(h,'Units','normalized','Position',[0 0 1 1],...
              'Data', defaultData,... 
              'Tag','myTable',...    
              'ColumnName', [],'RowName',[],...
              'CellSelectionCallback',@cellSelect);

% create pushbutton to delete selected rows
tb = uitoolbar(h);
uipushtool(tb,'ClickedCallback',@deleteRow);
end

function cellSelect(src,evt)
% get indices of selected rows and make them available for other callbacks
index = evt.Indices;
if any(index)             %loop necessary to surpress unimportant errors.
    rows = index(:,1);
    set(src,'UserData',rows);
end
end

function deleteRow(~,~)
th = findobj('Tag','myTable');
% get current data
data = get(th,'Data');
% get indices of selected rows
rows = get(th,'UserData');
% create mask containing rows to keep
mask = (1:size(data,1))';
mask(rows) = [];
% delete selected rows and re-write data
data = data(mask,:);
set(th,'Data',data);
end

It seems like you are trying to assign to a cell, rather than into a cell.

Here is what I would try:

data(:,5) = {true}

Or alternately:

[data{:,5}] = deal(true)

If you are still struggling read help cell.
