Move Environment to a table’s Options

Browse Source 
This commit moves the Environment field from the Table to its Options, and properly gets rid of the name ‘columns’ from the last commit.

Having it in the Options is important, because it means it can be generated from some command-line options. Also, it reduces the number of arguments that need to be passed to Table::new; there would have been 4 with the inclusion of the Environment, but by moving some of the code into the function, we can avoid this (and any further arguments).
