Formatted table shortcuts
Two of Excel keyboard shortcuts work differently in Formatted Tables (tables that are created using Format As Table icon on the Home ribbon)
Ctrl + Space normally selects the entire column(s). In a formatted table it selects the data in the column. Pressed again it selects the heading and the data pressed once more it selected the whole column.
Shift + Space normally selects the whole row(s), in a formatted table it will select the row within the table.
