...
You can use .eq() and .after() like this:
$('#my_table > tbody > tr').eq(i-1).after(html);

expression) does not have memory apart from the state it's in, and if

The definition of regular expressions is equivalent to the fact that a test of whe...

...T item)
{
T[] single = { item };
return single;
}
Or even better and shorter, just

{
yield return item;
}
Perhaps this is exactly what Enumerable.Repeat is doing under the hood.
