%s/\t/ /g

A leading colon is OK but not necessary. See

:help 41.1

In a Vim regular expression, a tab can be represented as \t. See

:help /\t

Depending on why and how you want to replace tabs by spaces, you may
want to take a look at

:help :retab
:help 'expandtab'

%s/^\s\+$//

See

:help /^
:help /\+
