Complain about inconsistent date columns

[frabcus]

I've got a personal file file (accounts/claimed-expenses/expenses-2010-10-09-francis.csv) which as a date column that contains dates.

Except the last row says "Total".

I think it could detect dates (a range of formats!), and complain if a column has dates in, but all rows don't have dates in.

Out of interest, how many rows are there in the table? Excluding the final "Total" one?

I've attached the file here: https://gist.github.com/frabcus/7edcd53ba901ecbac567
