Hi guys,

I'm currently checking if NatTable would be suitable for one of my projects. But I want the "numbers" on top and the headers on the left. In excel this is called transpose (I think).

I checked through all of the examples and non of them implements that. Also DefaultRowHeaderDataProvider only accepts a IDataProvider and not the possibility to add the "propertyStrings". Can I somehow switch the rows and columns using a layer or is this not possible?

Thanks in advance!

We do not have the functionality to automatically invert the axis. But if it is only about showing numbers in the column header and strings in the row header, you could simply implement a custom IDataProvider

Allright I got it sort of working using my own RowHeaderDataProvider and a custom GridLayer. But do I see it correct that I would need to rewrite most of the functionality like ListDataProvider, filters, sorting etc. to really get a "horizontal" table instead of a "vertical" table? Or do you have any tips to achieve this pretty easy?

Unfortunately not. As I said before, we started working on such an inverted table (or transposed), but failed with the several reasons. This is one of the reasons why we started thinking about a new architecture that is more related to axis than columns and rows. But the community seems to prioritize other things higher, so the completely new architecture is moved in favor of smaller improvements to achieve the new architecture step by step.

Sorry, I got off course. No there is no pretty easy solution and I even think a complete transposed matrix with all possible functionalities is quite hard to implement.

Dear Dirk, dear forum,

Is the described status still state of the art? Or is there now a way to transpose tables?

Thanks!
Stephan

Not sure if it is "state of the art", but there were no actions in that direction.

I know that the Papyrus project implemented such a feature in their context. But it is not trivial afaik and quite special to their data model.

Thanks!

[EDIT] I've managed to create a simple version of a table that has items in (say) one row rather than one column, by basically overriding ListDataProvider and swapping row and column information.
