Go to http://dynamictyped.github.io/Griddle/externalData.html and scroll to the first example that has settings enabled. Toggle the Settings view and then toggle and untoggle the id column. It will disappear from being the first column in the table and then when it reappears it will be the last column in the table. The ordering of the columns should be maintained. Ordering is maintained in examples that do not use external data, so this seems to only be relevant to external data.
