# YUI Library Examples: DataTable Control: Conditional row coloring

# DataTable Control: Conditional row coloring

This example demonstrates how to color DataTable rows based on data in a Record. In this case, rows with Quantity less than 40 are highlighted.

View example in new window.

## CSS

We apply custom CSS for a simpler looking table so the marked rows can really stand out.

/* Remove row striping, column borders, and sort highlighting */ .yui-skin-sam tr.yui-dt-odd, .yui-skin-sam tr.yui-dt-odd td.yui-dt-asc, .yui-skin-sam tr.yui-dt-odd td.yui-dt-desc, .yui-skin-sam tr.yui-dt-even td.yui-dt-asc, .yui-skin-sam tr.yui-dt-even td.yui-dt-desc { background-color: #fff; } .yui-skin-sam .yui-dt tbody td { border-bottom: 1px solid #ddd; } .yui-skin-sam .yui-dt thead th { border-bottom: 1px solid #7f7f7f; } .yui-skin-sam .yui-dt tr.yui-dt-last td, .yui-skin-sam .yui-dt th, .yui-skin-sam .yui-dt td { border: none; } /* Class for marked rows */ .yui-skin-sam .yui-dt tr.mark, .yui-skin-sam .yui-dt tr.mark td.yui-dt-asc, .yui-skin-sam .yui-dt tr.mark td.yui-dt-desc, .yui-skin-sam .yui-dt tr.mark td.yui-dt-asc, .yui-skin-sam .yui-dt tr.mark td.yui-dt-desc { background-color: #a33; color: #fff; }

## Markup:

<div id="tbl"></div>

## JavaScript:

A custom row formatter is used to examine for Records where Quantity is less than 40 and apply a CSS class to the TR element to turn it a different color.

YAHOO.util.Event.onDOMReady(function () { // Create a shortcut var Dom = YAHOO.util.Dom; // Contain our code under the YAHOO.example namespace var Ex = YAHOO.example; // Create the DataSource Ex.dataSource = new YAHOO.util.DataSource(Ex.Data.inventory); Ex.dataSource.responseType = YAHOO.util.DataSource.TYPE_JSARRAY; Ex.dataSource.responseSchema = { fields : ['SKU','Quantity','Item','Description'] }; // Define a custom row formatter function var myRowFormatter = function(elTr, oRecord) { if (oRecord.getData('Quantity') < 40) { Dom.addClass(elTr, 'mark'); } return true; }; // Instantiate the DataTable. Ex.dataTable = new YAHOO.widget.DataTable('tbl', [ {key:'SKU',sortable: true}, {key:'Item',sortable: true}, {key:'Quantity',sortable: true}, {key:'Description',sortable: true} ], Ex.dataSource, {formatRow: myRowFormatter}); // Enable the row formatter });
