Normal capacity on your standard issue 737-800 airliner (note: airliner) will be 20820 kg - you will notice that this is the lowest capacity listed.
20820 KGs is what you can load to the wing tanks (just shy of 4 tonnes each in NG) plus center tank (13 tonnes)
Now why did I say to note airliner - the table includes BBJ2 variant, that is a common user of auxiliary tanks.
You can install several of those (up to 9) in your baggage holds, sacrificing baggage space (not really needed on BBJs anyway). Those will take you to the other fuel capacities for the BBJ, up to a maximum of 31.7 tonnes.
You will see on the graph that they become useless after certain amount of payload, as you cant fill them with fuel anyway as it would take you over maximum take-off weight of 79 tonnes.

Just elaborating on what Fabo said...
The flat line is Max Zero Fuel Weight payload range... ie: Shove whatever payload you can...
The first sloped line, is the max brake release weight line... this is, where you have to start off loading payload for fuel to get more range.
The second slope line, is the max fuel line,... this is where you fill the tanks to the max, and still have to off load payload to get more range.
