public class TableNode
extends DiagramNode

Tables are diagram nodes that can contain multiple cells and can be related to other nodes through their rows.

Links can link either to table rows or to the table as an integral node. Use the setConnectionStyle(int) method to specify whether links drawn by the user should be connected to the table rows or to the table itself.

Tables consist of Cell instances distributed across rows and columns. The number of rows and columns can be set via the setRowCount(int) and setColumnCount(int) methods. The default width of the table columns is specified through setColumnWidth(float) and the default height of the rows through setRowHeight(float). Cells can be made to span several rows and columns via their Cell.setRowSpan(int) and Cell.setColumnSpan(int) methods.

Rows can be assigned to distinct sections of the table. Each section can be collapsed or expanded, hiding or showing all rows in the section except the header one. To define a section, call the Row.setHeader(boolean) method. A section consists of all rows after a header row and spans to the next header. Each header row displays a +/- mouseButton that allows expanding or collapsing the section interactively. The mouseButton appears either on the left of the first cell of a header row or in a separate column, as specified through the setOffsetHeaderRows(boolean) method. Sections can be collapsed or expanded programmatically using the Row.setExpanded(boolean) method of their header rows.

The structure of a table can be changed dynamically by adding and deleting rows and columns. This can be done with the addColumn() and addRow() methods as well with the insertColumn(int), insertRow(int) and redimTable(int, int) methods. Use the deleteRow(int) and deleteColumn(int) methods to delete existing rows and columns.

Tables have a caption text, which is set via the setCaption(java.lang.String) method. The height of the caption and the alignment of the text are specified via the setCaptionHeight(float) and setCaptionFormat(com.mindfusion.diagramming.TextFormat) methods. To get even richer text formatting, call setEnableStyledText(boolean) and embed HTML-like formatting tags in the caption.

In order to set an image as tables background, call the setImage(java.awt.Image) method. The alignment of the image in relation to the tables rectangle is set via the setImageAlign(int) method. The table can be resized to fit the size of its image by calling the resizeToFitImage() method.

Tow rows and columns of a table can be accessed through the getRows() and getColumns() methods. The getCell(int, int) method lets you access individual table cells.
