title: PyTable Column Order
body: <p>Is there a way to create a PyTable with a specific column order?</p>
  
  <p>By default, the columns are alphabetically ordered when using both dictionary or class for schema definition for the call to createTable(). My need is to establish a specific order and then use numpy.genfromtxt() to read and store my data from text. Unfortunately, my text file does not have the variable names included in the same way that the file data is.</p>
  
  <p>At this time, my column are ordered alphabetically and the data is misaligned in that it is ordered according to the file layout. And it is desirable to maintain the same order in the pyTable (but, not essential).</p>
  
  <p>Thanks</p>
