macro to keep specific name colomns and delete all others

[myshak]

Hi,
I have following file.

===================================================================
Item Feb1
Feb2 and so on
Qty Amt Dep COST COGS Qty Amt Dep Cost COGS
cup 1 3 3 234 23 4 4 3 234
23
coffee 2 5 3 23 56 5 2 3 234 23
paper 3 2 3 23 56 7 8 3 234 23

===================================================================

Important Each col except "item" contains sub- colomns (i.e Qty
Amount %ofDep AvgCost COGS AvgCOGS). I need to
keep col name Item. I need to keep col name Qty and Amount. I want to
delete all other colomns i.e Amt, Dep,Cost, COGS, There are ALSO
several blank titles colomns also which i want to delete.

Required file
