Refreshing ui_table

Dashboard
1

When I click twice on the Error button, why does it show only one entry in the table, and after a manual refresh, why does it show both entries?
How to fix it?

Have you looked at the ui-table examples, you will find them in editor.
Press ctrl I > examples > ui-table
Take a look at commands on how to add a row.

Did you mean the example on that site?

Ctrl+i or Ctrl+L seems not to be working properly (is it 'i' or 'L'?).
Additionally, I have implemented that function (to add row), but it appears not to solve my problem.

var controlMsg = {
    ui_control: {
        callback: 'update',
        tabulator: {
            addRow: newRow
        }
    }
};

No, in the node-red flow editor press control I or select import in the side menu

The command flow has examples of adding rows.
