i have this code
var allRows = document.getElementById(''upltab'').getElementsByTagName(''tr'');
var lastRow = allRows[allRows.length-1];
var root = lastRow.parentNode;
var newRow = root.appendChild(lastRow.cloneNode(true));
which will add a new row in the "upltab" table when called from an onClick event in a button.
what i want to do is also allow for subrows - so i need another function that will receive information on WHICH row was selected based on a link in the row itself and will add a subrow under just that main row rather than at the end of the table.
