Making cell references to individual table cells

[dan9933]

So I am using JavaScript to make a table on a page and what I want to do is have the JavaScript create the table, and then allow the user to fill it with data. I have been able to make the JavaScript create the table, my question is how to reference the cells in my script that adds data to the cell. I want the users to be able to click a button an add data into different cells so i figured giving them each an Id and referring to that Id in the button is the best way to do it.

How can I edit my code to give each cell a different Id? Or is there a better way of doing this?
My table code looks like this (i have filled it with random data so it is not just a blank table).

<code>
<script type="text/javaScript">
window.onload = fnInit;

function fnInit()
{
// Declare variables and create the header, footer, and caption.
var oTable = document.createElement("TABLE");
var oTHead = document.createElement("THEAD");
var oTBodyam = document.createElement("TBODY");
var oTBodypm = document.createElement("TBODY");
var oTFoot = document.createElement("TFOOT");
var oCaption = document.createElement("CAPTION");
var oRow, oCell;
var i, j;

// Declare stock data that would normally be read in from a stock Web site.
var heading = new Array();

heading[0] = "";
heading[1] = "Monday";
heading[2] = "Tuesday";
heading[3] = "Wednesday";
heading[4] = "Thursday";
heading[5] = "Friday";
var block = new Array();

block[0] = "8:30";
block[1] = "9:55";
block[2] = "11:20";
block[3] = "12:45";
block[4] = "2:10";
block[5] = "3:35";
block[6] = "5:00";
block[7] = "6:30";
var stock = new Array();

stock[0] = new Array(block[0],"88.625","85.50","85.81","99.54","55.46");
stock[1] = new Array(block[1],"102.75","97.50","100.063","49.54","55.46");
stock[2] = new Array(block[2],"56.125","54.50","55.688","99.54","55.46");
stock[3] = new Array(block[3],"71.75","69.00","69.00","99.54","55.46");
stock[4] = new Array(block[4],"71.75","69.00","69.00","99.54","55.46");
stock[5] = new Array(block[5],"71.75","69.00","69.00","99.54","55.46");
stock[6] = new Array(block[6],"71.75","69.00","69.00","99.54","55.46");
stock[7] = new Array(block[7],"71.75","69.00","69.00","99.54","55.46");

// Insert the created elements into oTable.
oTable.appendChild(oTHead);
oTable.appendChild(oTBodyam);
oTable.appendChild(oTBodypm);
oTable.appendChild(oTFoot);
oTable.appendChild(oCaption);

// Set the table's border width and colors.
oTable.border=1;
oTable.bgColor="lightslategray";

// Insert a row into the header and set its background color.
oRow = document.createElement("TR");
oTHead.appendChild(oRow);
oTHead.setAttribute("bgColor","lightskyblue");

// Create and insert cells into the header row.
for (i=0; i<heading.length; i++)
{
oCell = document.createElement("TH");
oCell.innerHTML = heading[i];
oRow.appendChild(oCell);
}

// Insert rows and cells into bodies.
for (i=0; i<stock.length; i++)
{
var oBody = (i<3) ? oTBodyam : oTBodypm;
oRow = document.createElement("TR");
oBody.appendChild(oRow);
for (j=0; j<stock[i].length; j++)
{
oCell = document.createElement("TD");
oCell.innerHTML = stock[i][j];
oRow.appendChild(oCell);
}
}

how about:

cellcount=0
// Insert rows and cells into bodies.
for (i=0; i<stock.length; i++)
{
var oBody = (i<3) ? oTBodyam : oTBodypm;
oRow = document.createElement("TR");
oBody.appendChild(oRow);
for (j=0; j<stock[i].length; j++)
{
oCell = document.createElement("TD");
oCell.innerHTML = stock[i][j];
oCell.id="cellno"+cellcount++
oRow.appendChild(oCell);
}
}
