When you have customized tables, often you restrict to 1 element the elements which can be presented in the table. So you know which columns will appears in your table, and all these columns will be created with the first drop in the table. In this case, it should be interesting to define the order of these columns in the tableConfiguration file. I propose to add the following field to this file : <eStructuralFeatures xsi:type="ecore:EReference" name="columnOrder" upperBound="-1" eType="ecore:EClass http://www.eclipse.org/emf/2002/Ecore#//EStructuralFeature"/> This field will be used to define the column order, but only when the first element is added to the table. We shouldn't reuse it for others elements for 2 main reasons : 1/ the user can have change the column order between the first and the 2nd dropped element 2/ If many kind of elements can be dropped into the table, the 2nd element can add columns, I think that these columns should be added at the end of the table.

This looks to complicate to be easily to understand by the users (without reading the documentation) I think that it would be better to create all the columns declare by the user when no column exists in the table, even if the table contains no row. The additional reference’s type must be ETypedElement otherwise we will not be able to managed the operations. <eStructuralFeatures xsi:type="ecore:EReference" name="columnOrder" upperBound="-1" eType="ecore:EClass http://www.eclipse.org/emf/2002/Ecore#//ETypedElement"/> Regards, Grégoire
To anticipate the API freeze I've updated the meta-model. Committed revision 1769.
