Hi team,
I take the code from table layout example,
I’ve some problem in positioning cells within the column or row group, here’s my diagram
and here what I’m trying to achieve:
My questions are:
- why cells’ border are not filled when there’s no adjacent cell on the right? (probably I’ve forget some settings)
- why there’s an empty cell after column/row title in both cases?
Here my code:
myDiagram =
$(go.Diagram, "myDiagramRep",
{
layout: $(TableLayout,
$(go.RowColumnDefinition, { row: 1, height: 22 }), // fixed size column headers
$(go.RowColumnDefinition, { column: 1, width: 22 }) // fixed size row headers
),
"InitialLayoutCompleted": function(e) {
// if not all Nodes have real locations, force a layout to happen
if (!e.diagram.nodes.all(function(n) { return n.location.isReal(); })) {
e.diagram.layoutDiagram(true);
}},
"SelectionMoved": function(e) { e.diagram.layoutDiagram(true); },
"resizingTool": new LaneResizingTool(),
// feedback that dropping in the background is not allowed
mouseDragOver: function(e) { e.diagram.currentCursor = "not-allowed"; },
// when dropped in the background, not on a Node or a Group, cancel the drop
mouseDrop: function(e) { e.diagram.currentTool.doCancel(); },
"animationManager.isInitial": false,
"undoManager.isEnabled": true
});
myDiagram.nodeTemplateMap.add("Header", // an overall table header, at the top
$(go.Part, "Auto",
{
row: 0, column: 1, columnSpan: 2,
stretch: go.GraphObject.Horizontal,

},
$(go.Shape, { fill: "transparent", strokeWidth: 0 }),
