Table visualization sorts by column type and not by display type

[gabrieldutra]

Issue Summary

Table visualization sorter is based on the type information provided by the server and not on the display type from visualization settings.

Steps to Reproduce

1. Create a query with String numeric values and change the display type for the column to "Number" (or just use this query)
2. Sort the query by that column and verify that the order is alphabetical and not numeric.

Example:

I expect it to use the display type to do that, otherwise the user doesn't have an UI control of that.
