# ColVis
  
  ColVis adds a button to the toolbars around DataTables which gives the end user of the table the ability to dynamically change the visibility of the columns in the table:
  
  * Dynamically show and hide columns in a table
  * Very easy integration with DataTables
  * Ability to exclude columns from being either hidden or shown
  * Save saving integration with DataTables
  
  
  # Installation
  
  To use ColVis, first download DataTables ( http://datatables.net/download ) and place the unzipped ColVis package into a `extensions` directory in the DataTables package. This will allow the pages in the examples to operate correctly. To see the examples running, open the `examples` directory in your web-browser.
  
  
  # Basic usage
  
  ColVis is initialised using the `C` option that it adds to DataTables' `dom` option. For example:
  
  ```js
  $(document).ready( function () {
      $('#example').dataTable( {
          "dom": 'C<"clear">lfrtip'
      } );
  } );
  ```
