title: How to use Cognos report studio creating a list with dynamic columns?
body: <p>I need to create a table list in cognos, but the columns of this table would change depend on the data.I don't know how to do this. I just know in cognos report studio, we can drag data into cognos list report.</p>
  
  <p>Update:
  I don't know how many columns in this table.Because different data generate different number of columns.Actually,one row of data is a tree hierarchy.For example,the first columns is root,the second column is its child,and maybe the third columns is second child,or first grandson,and so on.So the columns always change.</p>
