title: What's the best way to store "spreadsheet data" in MySQL
body: <p>I'm looking to store spreadsheet type data in a mysql database.  Basically it would be a grid, with x/y coordinates, and each cell can have various different properties to it.</p>
  
  <p>The grids can be of all different sizes, and I'd like this system to be fast and flexible, though some sort of caching isn't out of the question if necessary.</p>
  
  <p>Finally, a requirement of this project is to use mysql, and a restriction against any document style storage solutions(anything nosql really).</p>
  
  <p>I'm curious if anyone has any sort of standard solution for this that I'm not seeing.  I'd like to avoid a big table along the lines of column1_data1 column1_data2 column1_data3 etc etc for however many columns I can safely account for.</p>
