Progress control

[charga]

Recently begin to use spectre.console in my console applications. Begin using the Progress example beacuse I need to display the elapsed time for each of the task that I have, but allways (using ElapsedTimeColumn) and always display the same value and at finished all tasks, all display the same valie)
Here is my goal:
Base on a list of task, every task finished, need to display the time who consume, the total elements procesed (I solve that) and when all finished the accumulated total time.
Actual output:

Reading TUBERIAACERO class ---------------------------------------- 100% (279) (00:00:11.9887527)
Reading TUBERIAP80 class ---------------------------------------- 100% (231564) (00:00:11.9885658)
Reading TUBERIAP100 class ---------------------------------------- 100% (3337) (00:00:11.9885767)
Reading CRUCE class ---------------------------------------- 100% (82125) (00:00:11.9885873)
Reading ACOMETIDA class ---------------------------------------- 100% (226) (00:00:11.9885964)
Reading edge class ---------------------------------------- 100% (100) (00:00:00.0071767)

Also create a custom ProgressColumn

public class TotalColumn : ProgressColumn
{ public override IRenderable Render(RenderOptions options, ProgressTask task, TimeSpan deltaTime)
{
if (task.IsFinished)
{
var total = task.MaxValue.ToString(CultureInfo.DefaultThreadCurrentCulture);
string elapsed = string.Empty;
elapsed = task.ElapsedTime.ToString();
return new Markup($"white ({elapsed})[/]");
}
else
return new Markup("white[/]");
}
}
Any advice? Thanks in advance
