Yii CGridView custom export function

I need a simple plugin created for my existing yii1.6 software. I need the option added to every cgridview in my framework to export data to csv or pdf. 1. the export must be seamless, single click from within the gridview. 2. must export ALL data in the query result, not just pagination data. 3. need simple way to specify the columns to be exported, which may be different from the gridview data, AND will be different in each view. 4. process must load in the background, or Yii Console, as im dealing with huge data volume and otherwise the data will timeout. This should be a simple yii plug-in, either as an extention or as a modification of the cgridview source. it must be simple to install, implement and customize. only bids with the word fluffy will be considered.
