You are using an Office installation with a French interface.
When you try to use the keyboard shortcuts that are listed in the online help, you may notice they have no effect or have a different effect than indicated in the online help for Excel 2007.
For example, if you select a column and press Ctrl+0 to hide it, the selected column is not hidden. Instead, all the cells of that column get an outer border.
The English online help:
Excel shortcut and function keys - Excel - Microsoft Office Online
as well as its French equivalent:
Touches de fonction et de raccourci d'Excel
mention that Ctrl+0 hides the selected column(s).
In order to work around this problem, use the ribbon commands or the contextual menu commands.
For example, in order to hide a selected column, right-click the selected column and choose Masquer (Hide) from the contextual menu.
