Is there a grid copy column to go along with the add column?

I could not find any documentation about setting up the plus / add column in the grid, but it is all over in the examples to have something like:

gantt.config.columns = [
    { label: "Task Name", name: "text", tree: true, width: 150, resize: true },
    { name: "add", width: 30, resize: true, hide: false }
];

Are there any other built in columns? Specifically, I’m interested in a “copy” column.

Also, it appears that the “add” column doesn’t show the plus sign on the task rows unless it is the last column. Is that a bug?

Hello,
the ‘add’ is the only built-in button, you can add a custom one and handle click event

Yes, currently it works that way. We’ll change this behavior in the nearest update
