Describe the bug
I have a table with lots of columns/rows. When a user submits an HTML form using "POST" request, my app query the database and renders the data into an HTML table.

Everything renders perfectly fine until I include the script that exports the table. When the export table is included it slows down rendering the page. The browse will keep giving me the following warning.

A web page is slowing down your browser. What would you like to do? [Stop it]  [Wait]

This issue sounds like #155 except #155 is just a bad ticket because this is a great plugin and I have been using it for a long time!

To Reproduce
Steps to reproduce the behavior:
Create an HTML table with lots of columns/rows. the page will come to a halt before it even finishes loading.

Expected behavior
I expect the page to load just fine with/without the table-export plugin.

The export script should not access the table in the DOM until after the page is loaded. Also, processing the table should only happen if/when the user clicks the "export" table. Not everyone using the web page will be exporting the data, so there is no need to add more load on the browser unless the user is trying to export the data.

Perhaps, you can create the export buttons after the page is loaded. But I would suggest delaying processing the table or initializing the rest of the script until the user clicks the export button. There may be a need to show a spinner during the export and prevent the export button from being clicked during the export just to avoid having to call the process more than once.
