How to add additional delimiter in BOM - HDL?

Hi,

         How can I add additional delimiter in BOM - HDL?  The delimiter present in my BOM - HDL are COMMA, SEMICOLON, COLON, SPACE, DOT, HASH # and TAB.  But on my colleague's pc, there is no TAB delimiter.  How can I add TAB delimiter in his pc?  By the way, we are using the same license.

Thanks,

Mabel
