Do you want to show a 7-day calendar in the day planner column format, like the day and work week views use?

It's easy. If you want to use this format always and forever, select all 7 days at the work week in Tools, Options, Calendar Options button. To view 7 days without changing your work week settings, select the first date in the Date Navigator calendar, then hold shift as you select the last day. (Use Ctrl+click to select non-continuous dates.)

You can also click and drag to select days, but over 6 converts to the 2 column week view. Selecting two or three full weeks displays the selected days in a calendar grid, with larger than normal rectangles for each day.
