Reporting Services :: Horizontal Table And Page Break

I have a dataset with 2 fields : code and value. I have a parameter that will give me the data to insert into the table I want to make. The number of rows is not fixed, so I couldn't create, for example, a table with a fixed number of rows.

I want to create some kind of table that will allow me to have cells that look like this :  "code" : "value" and have 3 of them (like 3 columns) before I switch to the next line (row). 

Just to make it clear, I'm not using any SQL requests here, data comes from XML.

It should look like this :

code1 : value1   code2 : value2   code3 : value3
code4 : value4   code5 : value5   code6 : value6
code7 : value7

and it'll go like this until I've used all the data.
