wrap text in TableNode cell

Is there any API similar to TextFormat for TableNode's Cell object in js library? I want to wrap text in tablenode cell.

Text wraps out of the box in my test, as long as rows are high enough -

Code
Select All
table.redimTable(3, 3);
for (var r = 0; r < 3; r++)
{
	table.getRow(r).height = 33;
	for (var c = 0; c < 3; c++)
	{
		var cell = table.getCell(c, r);
		cell.setText("cell text test test test test test");
		cell.setFont(new Font("Arial", 4 + r + c));
	}
}

I do not have word wrap by 'default'. See attachments.
In the first image, since there is some text to the side, I expect a "..." as an indication that there is some more text.

With what you suggested, I would have to manually calculate the size for each row whenever the diagram needs to update?

Try table's resizeToFitText method, passing true for keepCellWidth argument.

I am unable to find resizeToFitText with arguments for TableNode in my definitions file. There are resizeToFitText with arguments but only for ContainerNode and ShapeNode.
I am using diagram-library v3.3.6.

I can see it available on latest 3.3.7 NPM's version -

Code
Select All
/** Resizes the columns and rows so that the cells are large enough to fit their text.
 * @param ignoreCaption true to ignore caption text and consider only cells for table size, or false otherwise.
 * @param keepCellWidth true to preserve column widths and resize only row heights, or false otherwise.
*/
resizeToFitText(ignoreCaption: boolean, keepCellWidth: boolean): void;


along with whatever TableNode.resizeToFitText improvements are from this release -

(NPM and our officials versions differ due to NPM version format being very strict, not letting us use smaller increments for patches and such)

After updating to 3.3.7, I am not able to draw link between nodes. The createDiagramLink API throws the following error:

Try updating your mindfusion-common module from npm and / or clearing browser cache.

Updating to the latest library solves the wrapping issue. However, there is 1 issue.

I initially create the node using this code.
Code (Javascript)
Select All
this.diagram.getFactory().createTableNode(20, 80, 55, 30);


Then I use resizeToFitText(false, true) to wrap the text. The problem is that, if the text can fit without issue in the initially supplied width, it still shrinks the node to the text width. Is there a way to provide minimum width to the node so that it does not shrink further than that?

There isn't, you will need to resize it back to the min width after fitting text -

Code
Select All
var minWidth = ...;
node.resizeToFitText(false, true);
var nb = node.getBounds().clone();
if (nb.width < minWidth)
{
	nb.width = minWidth;
	node.setBounds(nb);
}
