"Disabling" an HTML table with Javascript

You could try javascript like:

function disable(table_id)
{
    var inputs=document.getElementById(table_id).getElementsByTagName('input');
    for(var i=0; i<inputs.length; ++i)
        inputs[i].disabled=true;
}

Try the below with Jquery

$("#freez").click(function(){
    $('#tbl1').find('input, textarea, button, select').attr('disabled','disabled');
});
$("#unfreez").click(function(){
    $('#tbl1').find('input, textarea, button, select').removeAttr("disabled");
});
