I want to create a table node with a single row and a single column. Something like the following.

TableNode mynode = diagram.getFactory().createTableNode(10, 10, 200, 60, 1, 1);
       mynode.setStyle(TableStyle.RoundedRectangle);
       Cell mycell = mynode.getCell(0, 0);
       mycell.setBrush(new GradientBrush(Color.WHITE, Color.GREEN, 90));
       mycell.setText("Single cell text string");
diagram.add(mynode);

TableNode is created, showing the caption "Table" on top, the green row showing the my text string below the caption, but then below this green row, there is an extra row that I don't want. I just need the table caption and on single-column row.

Thanks. Yes, that does it. But there is another strange behavior. The cell text is not shown when I set the cell height exactly as (tableHeight - captionHeight). If I take 1 unit off, then I see the text but there is an extra area at the bottom that I want to remove.

final int TABLE_WIDTH = 100;
final int TABLE_HEIGHT = 30;

TableNode mynode = diagram.getFactory().createTableNode(0, 0, TABLE_WIDTH, TABLE_HEIGHT, 1, 1);
mynode.setBrush(new GradientBrush(Color.WHITE, Color.GREEN, 90));
mynode.setCaption("Parent Node");
mynode.getRows().get(0).setHeight(TABLE_HEIGHT - mynode.getCaptionHeight());
mynode.getCell(0,0).setText("Parent Node Text");
diagram.add(mynode);
      
TableNode mynode2 = diagram.getFactory().createTableNode(0, 0, TABLE_WIDTH, TABLE_HEIGHT, 1, 1);
mynode2.setBrush(new GradientBrush(Color.WHITE, Color.RED, 90));
mynode2.setCaption("Child Node #1");
mynode2.getRows().get(0).setHeight(TABLE_HEIGHT - mynode.getCaptionHeight()-1);
mynode2.getCell(0,0).setText("Child Node #1 Text");
diagram.add(mynode2);

diagram.getFactory().createDiagramLink(mynode, mynode2);
