Excel formating

I would like to style my excel spreadsheet, but am have a hard time understand the process. I have seen a couple examples:

        customize: function(xlsx) {
            var sheet = xlsx.xl.worksheets['Sheet1.xml'];
                 $('row:first c', sheet).attr('s', '42');
                 $('row c[r*="2"]', sheet).attr( 's', '25' );
           }

I know what they do but how do I interpret the code:

     'row:first c'  what does "c" mean?    // Style the first row Bold, green background, thin black border
     'row c[r*="2"]' what does "c" and "r*" mean?  // Style and row containing a 2 Normal text, thin black border

What if I wanted all rows to have normal text and thin black border?
What if I wanted the entire 2nd column have style 52 and 65?

Are there a couple of good examples postings or sites?
