Pls help newbie to include javascript in html head tag

Hi Javascript experts,
I downloaded this javascript off the internet to colour alternate rows of a table, and just had to add this script tag to the head of my html file for it to work (“<script type=”text/javascript” src=”tableDecorate.js”></script>”). However, can anyone tell me how I can include the javascript (given below) in the html source itself, rather than calling the external js file? Its probably pretty simple, but since I don’t know anything about javascript, I don’t have a clue how to do it. Please help!

//tableDecorate.js
// alternately you can place these in a script element..
var tableDecorate_rows = true;
var tableDecorate_columns = true;

function tableDecorate(e) {
if (!tableDecorate_rows && !tableDecorate_columns) return;
if (!document.getElementsByTagName) return;
var counter,
c, // columns
r, // rows
t; // tables
t=document.getElementsByTagName(“table”);
for (var i=0; i<t.length; i++) {
r=t[i].getElementsByTagName(“tr”);
for (var j=0; j<r.length; j++) {
// add “oddRow” class to odd rows
if (tableDecorate_rows && (j % 2 == 1)) {
r[j].className = “oddRow ” + r[j].className;
}
if (tableDecorate_columns) {
c=r[j].childNodes;
counter = 0;
for (var k=0; k<c.length; k++) {
// node must be element, not whitespace
// add “oddCol” class to odd cells
if ((c[k].nodeType == 1) && (counter++ % 2 == 1)) {
c[k].className = “oddCol ” + c[k].className;
}
}
}
}
}
}

// alternately you can call the function directly (after onload)..
if (window.attachEvent) {
window.attachEvent(‘onload’,tableDecorate);
} else if (window.addEventListener) {
window.addEventListener(‘load’,tableDecorate,false);
}

Thanks a lot,
