Jack,

Sorry I can't be more explicit, but this will point you in the right
direction. Using the JavaScript DOM model, you can assign the table(s)
you need to count rows for an id (for example, <table name="mytable",
id="table1">). Using DOM, you can directly access the table and count
the number of <td> tags that appear within. Obviously, each <td></td>
set is equivalent to 1 row.

Pass the id of the table to count the rows of. Get the rows
collection, then its length:

function numRows(t) {
if(document.getElementById) {
alert(document.getElementById(t).rows.length);
} else if (document.all) {
alert(document.all[t].rows.length);
}
}
