How to programmatically merge cells

[x68507]

This is a super simple question, but how can I programmatically merge a range of cells after rendering the data. I don't want to rely on the user to select the cells and I don't know I want to merge the cells until I get additional data back from the server, so this needs to be done after the loadData() method.

Also, is there an actual published API or tutorial somewhere? The ReadMe isn't enough to actually do anything useful.

Use getData and refresh the data:

var data = xs.getData();
data[0].merges.push("A1:B2");
xs.loadData(data);
