This document provides an overview of JTable in Java, including: - JTable displays data in rows and columns and allows resizing and reordering of columns. - It relies on classes like JScrollPane for scrolling and uses models like TableModel and TableColumnModel to define data and column characteristics. - Events like ListSelectionEvent and TableModelEvent are fired when the user selects or changes data in the table. - To create a basic JTable, you construct an instance, add it to a JScrollPane, and add the scroll pane to the GUI container. This allows scrolling of large tables.
