How to reference named table or code block in Org-mode

Question

In Org-mode buffers, table or code block can have #+NAME: title. But I don't know how to reference them in current buffer or in other files with org-mode hyperlink. (like one link format: [[file:some-file.org::*headline]])

Org-mode has support for some Custom Search functions. By default, Org-mode does not supprt this.

Does anybody knows how to add this support?

I found the solution, Org-mode radio target can be used here. here is the doc: http://orgmode.org/org.html#Internal-links Like this:

Here is a named table.

#+NAME: my target
| x | y |
| 1 | 2 |

I can reference it with its name. Like this:
[[my target]]

There are also table remote references further explained by an example in the following.

First we define a table with a name TBL_origin to have something to play with. The two numbers in the row Average are referenced in the tables further below.

  #+NAME: TBL_origin
  | Leaders  | Caption 1 | Caption 2 |
  |----------+-----------+-----------|
  | Average  |        16 |        17 |
  |----------+-----------+-----------|
  | Leader 1 |        11 |        12 |
  | Leader 2 |        21 |        22 |
  #+TBLFM: @2$2=vmean(@II$2..@III$2)::@2$3=vmean(@II$3..@III$3)

The vector of the two numeric cells in row Average of table TBL_origin are referenced in the table formulas of the next tables.

  | Use table reference |
  |---------------------|
  |                16.5 |
  #+TBLFM: @2$1=vmean(remote(TBL_origin,@2$2..@2$3))

Note that you can not directly assign remote references to table ranges (see the posting Re: [Orgmode] remote reference in the orgmode mailing list).

A workaround is demonstrated in the following table:

  | Refer to averages |
  |-------------------|
  |                16 |
  |                17 |
  #+TBLFM: $1=subscr(remote(TBL_origin,@2$2..@2$3),@#-1)
