Support for header groups

[JTFlavier-Cob]

Hello there! Thank you for creating this library. It has been very helpful.

Does this library currently support header groups? I am using react-table to render tables with header groups that look like this (this table goes on until December):

The JSON input for react-table looks something like this:

[
    {
        name: "Alpha",
        age: 23,
        sex: "F",
        salary: 3213, 
        months: [
            {
                month: "Jan",
                income: 12312,
                expense: 23,
                profit: 12289
            }, 
            {
                month: "Feb",
                income: 345624,
                expense: 23,
                profit: 345601
            },
            ...
        ]
    },
    ...
]

By setting up react-table's columns parameter in a nested manner, I am able to make the table seen above.

Given the data structure above, is it possible for me to export an excel file that looks like the example?

unfortunately, it is not supported with header columns, only way was the one you already tried :)
