Web Query and storing data

Hi all
I'm quite new on web queries so i don't really know how to procede sometimes. All i need to do is to take values from a tables of a webpage (for example this: https://www.betfair.es/exchange/plus...et/1.122474308 ) and store datas in excel. I have two problems, first of all when the web query refresh the data, the data are overwritten, and i don't want this, i want to store them and write the new one somewhere else(for examble below the previous one). The second problem is that the table is actually not recognised from excel and i import the entire page and the values i need happens to be from A57 to F58 ( is a 2x6 set of values i need to store). There is a way to build a macro to do all this job and write me the values in a clean an ordered way ?
Thanks in advantage.
