ExtJS 4 - How to add background colors to columns of a grid?

I have a grid in which I need to provide different background colors to various columns.

These column colors should also not be overwritten by the mouse-over color.

I have tried using cls and tdCls but no luck.

Could anyone guide at how this could be achieved?

Thanks in advance.

add this to whatever column you want to change color

renderer:function(value,metaData){
    metaData.style="background-color:#EAA8A8";
    return value;
},

You do not need a renderer for this. What's happening is that ExtJS's zebra striping style (x-grid-row-alt) and mouse over style take precedence over the style you defined in tdCls. Add !important to the background color and it'll work. For example:

.my-column-style {
    background-color: blue !important;
}

NetEmp is right here, you want a renderer and you want to use the direct 'style' method or I did it below using the following:

function greyRenderer(lpValue, opMeta, opData) 
{

    if (opData.data["Condition"] == 0) {
        opMeta.attr = "style='color: #aaa';";
    }

    lpValue = Ext.util.Format.htmlEncode(lpValue); 
    return lpValue;
}

Note here I check the value on the row in a particular field and then apply the colour to the foreground text and html encode the output, you can obviously just switch things to your specific requirements.
