Checking row data against others rows data

Rolighed

Pleease help.

So, I have a datatable with X rows. In it I have a column named "Weight".
When I render my "Weight" Column for a Row, I want to check if the weight (data) for this Row is the lowest value of all Rows. I only want to look at/compare to "visible" Rows, so filtered Rows should be ignored. However, Rows on other pages should be included if paging us used!

I suspect I should do something in the render method in my columnDefs? In line of...:

"render": function (data, type, row) {
    if (type == "display") { 
        if (ISLOWESTWEIGHT) {
            return "<i class='fa fa-trophy'></i> " + data; 
        }
        else { 
            return data; 
        }
    }
}
