you can use the query analyzer, select database --> user tables --> select correct table --> right click --> script object to new window as -->> create. The query analyzer will generate a script that will generate your table.
At the left side is the object browser. If you cannot see, push the F8 button. You see at the top your server and below the databases in that server. From that point on it's like the Windows Explorer. When you see the user tables you can select one and right click on it for the scripting.
don't know, never used sql 7. Something else you can try: in the enterprise manager, select the table you want to script. Right click on it, select all tasks and then generate script. A popup will appear and if you want you can set some preferences, but just pushing OK is sufficient. Hopefully this is in sql 7
