Can I access my tax tables after I install TaxJar for WooCommerce?

When you install TaxJar, you may notice that you no longer have the ability to edit your native tax tables and the links under WooCommerce -> Settings -> Tax to add rates to your tables are now hidden.

We do this to ensure that proper rates are added to your tax tables and your customers receive live rates from our service when they are in the checkout page of your store.

If you deactivate the plugin, those links will come back and you'll be able to continue editing the rates on your own.  If you want the rates that you had prior to installing TaxJar, you'll want to  read this article which shows you how to grab a CSV file of those rates.
