How to get table id in drawCallback

mp108

I want to style <td> elements in a column <th> named "Change" and do this in the function called for 'drawCallback' option which is passed this.api().

I cannot see any way to access column headers from this.api() object so once I know the table's id, I select the <th> for it.

By examining the this.api() object, I found two ways to achieve this but am wondering is there a documented function to either give me the column headers or the table id?

How I get table id from this.api()

function adjustTableWidth(api){
    :
    var tableId = api.tables().nodes().to$().attr('id');


function decorateTable(api){
    var tableId = api.context[0].sTableId;;

By the way, call back option in my dataTable definition:

'drawCallback': function( settings ) {
    var $nTable = $(tableId);
    // do some stuff

    // call callback function
    if(fnDrawCallback){
        fnDrawCallback(this.api());
}
