When you create a new data package that includes a data file that is TAB
delimited, the ascii import works well, and the copy of the data file sitting in
the user's local profile data store is identical to the original. However, when
it's viewed by pressing the 'View Data' button within the editor, the
spreadsheet viewer incorrectly renders lines with missing values. It actually
just shifts cell values to the left if there are missing values to the left:

a <TAB> 1 <TAB> x
b <TAB> 2 <TAB> y
c <TAB> <TAB> z
A <TAB> 4 <TAB> X
<TAB> 5 <TAB> Y
C <TAB> 6 <TAB> Z

gets rendered as:

a 1 x
b 2 y
c z
A 4 X
5 Y
C 6 Z
