A got src block
#+NAME: gdt
#+BEGIN_SRC ruby :var date="14-05-2018"
require 'active_support/all'
table_header_days = []
today = Date.parse(date)
0.upto(7 - today.wday) do |n|
table_header_days.push("#{(today + n.days).day} #{(today + n.days).strftime('%a')}")
end
[['', table_header_days, ''].flatten, nil, ['row 1'], ['row 2'], ['row 3'], ['row 4']]
#+END_SRC
It outputs like table
#+RESULTS: gdt
| | 14 Mon | 15 Tue | 16 Wed | 17 Thu | 18 Fri | 19 Sat | 20 Sun | |
|-------+--------+--------+--------+--------+--------+--------+--------+---|
| row 1 | | | | | | | | |
| row 2 | | | | | | | | |
| row 3 | | | | | | | | |
| row 4 | | | | | | | | |
I want to use this src block in other src block
#+BEGIN_SRC ruby :noweb eval :exports table
<<gdt("14-05-2018")>>
#+END_SRC
I expect to get table but got an error

What I did wrong?
The only thing you can use inside the <<...>> markers in a noweb "call" is a code ID, i.e. the name of the block that is to replace it. In particular, you cannot pass arguments like this <<gdt("arg")>>.
Try changing your second block to this:
#+BEGIN_SRC ruby :noweb eval :exports table :var date="14-05-2018"
<<gdt>>
#+END_SRC
