When printing tens of thousands of lines, there is a performance issue. The TableRowCollection -> Add method was being called millions of times. Once it is called, it returns the index of the added element. As the element is added to a List (new List<TableRow>, I believe it is not needed to use IndexOf because it will be added always at the last position. Replacing the IndexOf call by a Count - 1 improves the performance in this scenario. Related issue: spectreconsole#975

No need to calculate the index of a new object in the collection if the position is always the (Count-1) after the addition.
The Add method at TableRowCollection is being called billions (US) of times for tens of thousands of prints.
