Using value formatters of type string while all values in a row are strings leads to formating for that row being skipped#37

I'm not sure that this is similar for other types, but the example below gives an bugged output for the string case: ``` public Void Run() { Table table = new TableBuilder() .AddColumn("one") .AddColumn("two") .RowFormatter<string>(Format) .AddColumn("three") .RowFormatter<string>(Format) .AddColumn("four") .AddColumn("five") .Build(); table.Config = TableConfig.Unicode(); table.Config = TableConfig.Unicode(); table.AddRow("1", "2","3","4", 123); table.AddRow("1", "2(\u2190test)","3(\u2190test)","test", 123); table.AddRow("1", "2(test)","3(test)","test", "123"); table.AddRow("1", "2(test)","3(test)","test", "123"); table.AddRow("1", "2(\u2190test)","3(\u2190test)","test", "123"); Console.WriteLine(table.ToString()); } private string Format(string test) { Color positive = Color.FromArgb(152, 168, 75); return test.ForegroundColor(positive); } ``` Output:  Expected result is that all lines would have the two green columns. Breakpoints show that the whole method is skipped in the incorrect rows.
