Describe the bug
Rendering is wrong in live rendering for hidden table headers & no border. The rendering starts on the wrong line (off by 1 line) when Refresh() is requested.

To Reproduce

using Spectre.Console;
var table = new Table().AddColumn("hidden").HideHeaders().NoBorder();
AnsiConsole.Live(table).Start(ctx => 
    {
        table.AddRow("toto");
        ctx.Refresh();
        table.AddRow("titi");
    });

Expected behavior
Rendering must start on correct line.
