Load CSV, Remove Columns, Dynamically Populate Menus & Display Filtered Result?

I have a new and seemingly huge new project to work onWe have a database that our database administrator is willing to run a script on nightly.The result of this action will be a CVS file containing information that is specific to my departments needs.At first, I need to present visitors to my site with a way to pear the data down to a more manageable sizePrior to displaying the CSV file contents, I thought I would display a set of column headers with checkboxes. Using the checkboxes, I'd like to give visitors to my site the ability to decide which columns of data they want to hide or display.

After they've made their selections and pressed an "OK" button, I'd like to display the remaining contents of the CSV file as a table in a seperate windowThe next part is very Excel like..At the top of each column, I'd like to include a series of drop down menus that visitors to my site can use to filter the list further.In my case, I don necessarily know every possible value for any given column. For example, imagine that one column contains city, another state and the third contains zip code. I could assume all 50 states in the union, however the actual data might also include Puerto Rico and the US Virgin islands. Or I might assume every zipcode in the US, however the actual data might include zip codes for Canada, etc... For this reason, I would like to populate the drop down menus dynamically.
