@Bjoern_Houlberg For the first table view, most likely the table view was automatically generated by AppSheet, and thus the view would use all of the default settings and sorting. If you want to customize the sorting in the table view, you will need to explicitly create it and then configure the sorting that you want. If you don’t want the created view to show up in either the app menu or the footer bar, you can set the view’s position to “Ref”. Also, you will need to point the data source of the view to the slice and not the source table.
For the 2nd table view after you have drilled down into the graph, it is possible that the underlying data source of the drilled-down graph is no longer the slice but is the source table instead. As such, the column order in the slice will not be applied to the table view. To verify this, you can run the app in the app emulator in the editor. Pay attention to the table name and view name at the bottom of the emulator to see which slice/table the view is using as its data source. If the graph and the table view were using the original table instead of the slice, then you will need to explicitly create a table view for the original table, and configure the column order and sorting of this view.
