To enter numbers into the table, select the Data/Matrix editor, and a screen will pop up. It will want you to enter a variable name. In mine, I chose 'c'. This simply is the name of each column in the table. When you hit enter, the table will appear, and numbers can be entered, much like in Microsoft Excel.
If you've already entered the numbers into the Data/Matrix editor, go to Y= screen and scroll above y1. At plot 1, hit enter and select what kind of plot type you want. Then for x and y, enter the variable above each column of the Data editor. (i.e. c1, c2...whatever variable you selected when the Data/Matrix editor was first used). Then hit enter and graph. Hope this helps.
