In the current 5.14RC, the sync properties allows to sync one TableView with another one. The suggested use is with the headers which are, in most use cases mandatory. Since we cannot sync with multiple TableViews, it renders impossible most of the time to have one synced header table AND another table with static columns (eg. fixed panes in Excel).

It would be nice to have a list of Synced TableViews to allow this kind of scenarios.
