When I put a function in my TI-83 Plus calculator like 2x-7 and press the "2nd" and "graph" button (table), the calculator shuts off and the screen goes blank. When I turn the calculator back on, it has "TI-83 Plus 1.19 " "RAM cleared" on the screen.

If you want the table to be generated, you must use the table feature. You can generate a table also after you draw (graph) a function. Enter a function in the Y= editor, then press GRAPH or SHIFT GRAPH (TABLE). If you press GRAPH, you will see a graph. If you want the table and are not interested in the graph, press SHIFT TABLE.
If you erase the second column of a table (whatever your reasons) you can regenerate it by reinserting the function in the Y= editor. Enter the function then press [2nd][GRAPH] to regenerate the table.
