any difference between table.row() and table.rows()

jfr

Hi

I am trying to look at the data of a row to see if there is any negative number in the rowCallBack

"rowCallback": function( nRow, aData, iDisplayIndex, iDisplayIndexFull ) {
    if (aData) {  
        console.log("*********** iDisplayIndexFull:"+iDisplayIndexFull)
        var rowColumns = oTable.row(iDisplayIndexFull).columns( ".sum_mnt, .sum_qty" );
        rowColumns.data().each( function ( value, index ) {
            console.log("rowColumns index:"+index+ " value:"+value)
        } );
        var rowsColumns = oTable.rows([iDisplayIndexFull]).columns( ".sum_mnt, .sum_qty" );
        rowsColumns.data().each( function ( value, index ) {
            console.log("rowsColumns index:"+index+ " value:"+value)
        } );
    }
}

both rowColumns and rowsColumns give me exactly the save result
I was hoping to have only 1 row of data with row(iDisplayIndexFull) or row([iDisplayIndexFull]) but I get the data of all rows

Am I wrong in my assumption or in my code ?
Thanks in advance

I don't think iDisplayIndex or iDisplayIndexFull are what you want - looking at the code (as those two parameters are undocumented - and therefore shouldn't be relied upon) neither is the row index - which is probably way you are running into the problem.

What you could do is use oTable.row( nRow ).data() to get the data for the row.

I knew rowCallback needed some work, but that really is a bit of a mess (in that it should give you the data directly, as well as the row index...).

Hi Allan
I did change the index by rRow
Still have the same columns selection

var rowColumns = oTable.row(nRow).columns( ".sum_mnt, .sum_qte" );

and it is still returning all rows of the table instead the a single row as the following

var rowsColumns = oTable.rows(nRow).columns( ".sum_mnt, .sum_qte" );

Thanks

Oh I see - you want to select cells based on a row and column selector? In which case use cells() and pass in your row and column selectors to it, rather than chaining rows() and columns() together, which will not work.
