89	89	1. Eclipse has now created your new plug-in and was nice enough to open the //Plug-in Manifest Editor//, which allows you to graphically edit two important files of your plugin: {{code language="none"}}plugin.xml{{/code}} and {{code language="none"}}META-INF/MANIFEST.MF{{/code}}. (By the way, this would be a great time to research the editor and the two files online.) Basically, those two files provide information that tell Eclipse what other plug-ins your plug-in needs and how it works together with other plug-ins by providing extensions and extension points. Our new plug-in will depend on two other plug-ins, so switch to the //Dependencies// tab of the editor and add dependencies to {{code language="none"}}org.eclipse.ui.editors{{/code}} and {{code language="none"}}org.eclipse.jface.text{{/code}}. Save the editor and close it. (You can always reopen it by opening one of the two mentioned files from the //Package Explorer//.)

	125	+The next task consists of creating a view that is able to display the state of a Turing Machine. We will do this using a table with one column, where each row represents an entry on the tape of the Turing Machine. The tape shall be infinite to one side, and the position of the read/write head shall be movable by two buttons. The content of the tape shall be determined by the currently active instance of our simple text editor.

	131	+== Creating the View Class ==
	132	+
	133	+We will start by creating a class that will define the view.

	135	+1.

	138	+Your TableViewPart contains a still empty method createPartControl. This method will be responsible for creating the user interface components of your view. Add the following code to create the table we want to display:

	140	+{{code title="createPartControl(...)" language="java"}}
	141	+Table table = new Table(parent, SWT.BORDER);
