Simple ui_table to sort "desc" on load

[gNeandr]

It should actually be easy, but I don't have the right view!
A block of strings with ("date", "value1", "value2") has to be sorted and displayed in a table (ui_table). Sorting should take place at load in descending order according to "date".
A flow without sort setting always displays the "date" column as ascending.

All my attempts with ui_control/tabulator fail. Surely it should be "simple"? But how ... please help

I tried it with this:

msg.ui_control = {
    "tabulator": {
        column: "date", dir: "desc" }
    }

... but failed.

The 'Tabulator' has something like this function:

   table.setSort("age", "asc");

I also don't know how to use it with ui_table/ui_control

If you are using node-red-node-ui-table
this example shows how to use commands.

or you can can use initial sort with the ui_control.tabulatore property

Tabulator - Sorting Data

Or
you can set a sort parameter to the column settings

Tabulator - Sorting Data

p.s. the tabulator in ui-table is 4.4 documentation.

Looks like I got a good guide with this.
Unfortunately my search was not so successful!
Thanks!

Just had the opportunity to successfully test a "function" adapted to my situation on the basis of your example. My function equivalent to "table with n rows as array" and "addRow @ top" is this one:

msg.payload = tabledata;
node.send(msg);

msg.payload = {
    command: "setSort",
    arguments: [
        [{ "column": "date", "dir": "desc" }]
    ]
}
return (msg);

I first send the data with the function using node.send(msg) and then the control for sorting the "date" column with the send(msg);
Maybe it works in one approach, but this way it is clear and simple for me

Thanks again for the help.

It is exactly the same approach, my example was set out so you could see it work in the dashboard. As you offered no flow example with data to adapt i created data to use in a demonstration.
