I am learning JS and after fiddling around with adding elements etc I tried to do an alert() with the object but instead got this error: [object htmltableelement] so I then tried:

alert(t.toString());

and got the same error... how can I see the contents of the object?

you can use firebug:

console.log(t);

or you can use innerHTML;

alert(t.innerHTML);

The way I normally do this is by using FireBug firefox add-on. Add a break point in your JavaScript then you can view any object and all its keys/values.

See everything:

for(var key in t)
  alert('key:' + key + ', value: ' + t[key]);

You may want to replace alert with console to avoid 100s of alerts

function domObjectToString(domObject){   
    if(typeof(domObject) ==='object'){    
        var divElement = document.createElement('div') ;    
        divElement.appendChild(domObject);    
        return divElement.innerHTML;    
    }else{     
        return domObject.toString();     
    }
}

---- steps follow -----
1. check the domObject Type [object]
2. If Object than
a. Create an "Div" element
b. append DomObject To It
c. get The innerHTML of the "div" it Gives The String
3. If Not an Object than convert to String and return it .

That is not an error. That is the default string representation of an object.

Either iterate through the object's properties and output them one by one, or use a proper debugging tool like Firebug that'll give you the ability to really examine your variables.
