Under the Preferences: Grader report tab in your grade book you can adjust how your Grader Report looks.
Within your course in Moodle open your grade book by selecting Grades from the Navigation block menu, click the Setup tab, and then click Preferences: Grader Report.
You’ll probably stick with the default settings; however, you can change any setting you’d like. To see an explanation of a setting, click the grey question mark.
Under General settings, Students per page is where you adjust the number of students displayed per page.
The Show only active enrollments setting is set to Yes by default. When enabled, suspended students will not show in the grade book.
When you are finished, click the Save changes button at the bottom of the page.
In the Grader report itself, you can toggle your view by course level, showing everything, just the course total, or everything but the course total; or by category level, showing everything, just the category total, or everything but the category total.
In the very top row of the Grader report, you will see the name of your course with an icon next to it. By default it is set to show everything, so the icon should look like a dash. Likewise, in the second row is your different grade book categories with the same icon.
Click the icon and your view will adjust to only showing the overall course total or for a category, the category total. The icon will now look like a plus sign.
Click the icon again and you will see everything but the overall course total or for a category the category total. The icon will now look like an empty square.
Click the icon one more time and you will return to the full view of everything.
