Then I would recommend just putting id attributes on each <td> and 
changing the cell contents. Any practical risk of making the cell update 
operation divisible that way must be ignorable when compared with the 
risks caused by added complexity of code.

But if an indivisible operation is really needed, then the simplest 
approach that avoids the IE bug is probably something like this:

function addCell(row,data) {
   var cell = document.createElement('td');
   cell.innerHTML = data;
   row.appendChild(cell);
}
function letters(a,b,c) {
   var boxId = 'box';
   var box = document.getElementById(boxId);
   var newRow = document.createElement('tr');
   newRow.id = boxId;
   addCell(newRow,a);
   addCell(newRow,b);
   addCell(newRow,c);
   box.parentNode.replaceChild(newRow,box);
}

No, all the three cells are <td> elements. If the real intent is to 
create something easily modifiable and extensible, then you might worry 
about the optimal way of retrieving all cells, or all data cells, in a 
table row, and looping through them, but the problem posed was specific 
and simple.
