Hi Sufian,
You can't do that in the paste operation, you need to Sort the column
after it is pasted. If the column is already in an ascending or descending
order, simply highlight the data, go to Data>Sort and check sort ascending
or descending.
If the data is fluctuating you will need to insert a helper column next to
it,
put 1 in the first cell, 2 in the second, then highlight both cells, grab
the
fill handle and drag down to the end of your data.
Highlight both columns and go to Data>Sort select the helper column
from the pulldown and check either ascending or descending.
You can delete the helper column when you finish.
