Xcalar Design will automatically hide uncommon fields from your table.
To see these fields:
1. Right click on a column and click 'Add a column'
2. Input some column name you want to call this column
3. In the function bar (looks like 'f(x)=') type pull(prefix:privileged)
And replace prefix with the expected prefix for your field. If you haven't done any joins on your table, it will just be the name above your other column names.
For example, in this picture, my prefix is 'parts'
