query for coloumn hiding in ALV

Hi all,

I am generating an ALv with 24 coloumns,but now I need to hide a field.

Its like the user should have the option to see the complete ALV or with that particular field hidden

example:

This is existing ALV:

GROUP G/L ACCOUNT LC USD

100 10 5 5

100 11 6 4

100 12 3 3

100 11 3 2

200 10 5 5

200 11 6 4

200 12 3 3

200 11 3 2

now there should be a option such that we can hide G/L account coloumn.

GROUP LC USD

100 5 5

100 6 4

100 3 3

100 3 2

200 5 5

200 6 4

200 3 3

200 3 2

some one please suggest how to do this.

thank you,
