Cross-reference table numbers in a sub-document

[lonoob]

Using a master document setup, you can easily reference chapters between subdocuments.

But how do you reference a table number from one subdocument in another subdocument? Is this about referencing number ranges or is there some kind of workaround?

Cross reference numbered paragraphs between documents

Hi, I have a couple of documents, each with some numbered paragraphs, that I want to cross reference. By means of example, I’d like to have bullet number 1 in document 1 cross-referenced by bullet number 1 in document 2. I tried using a master document but cannot seem to use numbered paragraphs for bookmarks or links, and yet I would like the references updated as they are when in the same document (either fully or semi-automatically). Can this be done? Many thanks, Richard ~

Cross-reference to numbered element in another subdocument

How can I insert cross-reference (with number) to a numbered element in another subdocument in a master document? The only solution I know is to manually create numbered list. Create a numbered range (in menu Insert->Fields->Other, select Variables, Number range), then use fields of this range to number elements in the list.

[Writer] Can we cross-reference a number range variable and label defined in table?

What I’m looking for

The table in the sub-document has a caption like "Table 4.2: A table containing everything"

And the reference should be "For any information see table 4.2" (only the number should be referenced, not ‘table’)

I know how to cross-reference in a master document setup. Referencing chapters works, but when I reference tables across subdocuments, I just get a blank field…

How is this done?

After some experimenting, the answer turned out to be simple.

1. mark the number range in the table caption (e.g. 4.2)
2. set a reference on the number range
3. insert references in other documents as usual

It works great, I don’t know why this and previous questions did not get an answer with a solution.
