infoCallback
Table summary information display callback.
Description
The information element can be used to convey information about the current state of the table. Although the internationalisation options presented by DataTables are quite capable of dealing with most customisations, there may be times where you wish to customise the string further. This callback allows you to do exactly that.
Please note that if the info option is disabled in the initialisation, this callback function is not fired.

3 endNo End position in data for the draw
4 maxNo Total number of rows in the table (regardless of filtering)

Examples
Show start to end indexes in the information element:
$('#example').dataTable( {
"infoCallback": function( settings, start, end, max, total, pre ) {
return start +" to "+ end;
}
} );Use the API in the callback to show page count:
$('#example').dataTable( {
"infoCallback": function( settings, start, end, max, total, pre ) {
var api = this.api();
var pageInfo = api.page.info();
return 'Page '+ (pageInfo.page+1) +' of '+ pageInfo.pages;
}
} );Related
