Hi,
The only solution I see is to override the views in order to create a specific design.
The idea is to display the prices and remove the "€" symbol from the returned text. So, the "€" symbol can be displayed in another cell in the table and the price can be displayed without the symbol.
At this moment, you will have aligned symbols and aligned prices.
But it requires some development skills (in order to modify the views correctly).
