Data Table Helpers

[jowers]

We should add in a set of procs to help handle different data table types.

Examples taken from pull request #14

| heading_1 | heading_2 |
| data 1 | data 2 |

| heading_1 | data 1 |
| heading_2 | data 2 |

and, of course, something with multiple values in:

| heading_1 | heading_2 |
| row_1 1 | row_1 2 |
| row_2 1 | row_2 2 |
| row_3 1 | row_3 2 |
