Hi,

The +/- icon's is not considered part of node's bounds by layout calculations. Its right side is at 5 mm distance from node's right border, so:

1. When calling resizeToFitItems after layout, pass a larger margin argument than 5 (if using default millimeter unit).
2. Set treeLayout.nodeDistance to a larger value too.

I suppose 3 shows the divider line between table's caption-bar and cell area, with CaptionHeight set to 0 and Shape set to RoundedRectangle. We'll fix it for official release to not draw divider when CaptionHeight is 0.

I hope that helps,
Stoyan

Try this:

var TableNode = MindFusion.Diagramming.TableNode;
var updateCanvasElementsOriginal = TableNode.prototype.updateCanvasElements;

TableNode.prototype.updateCanvasElements = function ()
{
    updateCanvasElementsOriginal.apply(this);
    var content = this.graphicsContainer.content;

    // look for divider Line object
    var index = -1;
    for (var i = 0; i < content.length; i++)
    {
        var contentElement = content[i];
        if (MindFusion.Drawing.Line.isInstanceOfType(contentElement))
        {
            index = i;
            break;
        }
    }

    // remove if found
    if (index > -1)
        content.splice(index, 1);
}; 

That code was using MS Ajax library. Replace it with this instead:

if (MindFusion.AbstractionLayer.isInstanceOfType(
    MindFusion.Drawing.Line, contentElement))
{
    index = i;
    break;
}
