@AndrewJBThere really is no specific order implied when iterating a clone collection. The clones are added in the order they match in my experience. In general this is in the order they appear in the HTML, but depending on how the rows are added, I have seen them appear in a different order. If you want to use this order, then there is an index property on the control you've cloned that you can use to get the order.

If you want to be explicit and order them yourself in a manner that would not change depending on how rows are added to the page, then the best way that I have found is to find something about the row that can indicate the order and use that. For example, there might be an index cell in the row's innerHtml property that you can use. You might have an attribute or other value indicating the order. If you don't, then you might also look into the "Location" property. You could use the Y coordinate to place fields in order. To iterate through them in order isn't terribly difficult, but here's a way that you could do that.

For the attached solution, I am using a Windows form to house the TableView, because in 19.1 the TableView control can only be added to a Windows Form. This is not the case in V21 (which is coming out soon, but for now this works). The Form is invisible, but you could of course add the TableView to any UI you might already have. I set the Opacity to 0 and the ShowInTaskBar to false to make the form invisible.

In the example, I am sorting by the Y coordinate in descending order (merely to make it visibly different than the default order since in this example the clone collection order matches the visual order). The sort field could be any string you can sort on though (or you can even get more complex with the TableView sorting.
