Adding Dynamic Rows To Table

I am working on some JavaScript that dynamically adds rows to a table
in response to a button click. A new row does appear on the screen
when the button is clicked. However, that table to which a row has
been added is itself contained within an outer table (to handle the
desired screen layout). That outer table does not properly grow to
contain the new size of the table to which the row was added. (More
specifically, I have sporadically seen the outer table grow correctly,
but then most of the time it does not grow as desired.) Is there
something that needs to be done in the code that will make the right
thing happen? (This phenomena appears in Netscape 7.1 -- things work
correctly under Internet Explorer 6.0)


A second anomoly concerns a button that appears in the newly added
row. An "onClick" event is associated with that dynamically added
button. The newly added button works correctly under Netscape 7.1 but
fails to work under Internet Explorer 6.0. (It is like Explorer will
not honor an event that is set in place by code that is dynamically
created after the page is loaded.) Shown below is an excerpt of the
code that is attempting to set up the desired button. Is there
something apecial that must be done in the code to get Explorer to
handle this properly (I have tried spelling things as both "onclick"
and also "onClick")?

tbldata = document.createElement("TD");
item = document.createElement("BUTTON");
v = 'doaction("Edit",' + n +')'
item.setAttribute("name","Edit");
item.setAttribute("onclick",v);
textitem = document.createTextNode("Edit");
item.appendChild(textitem);
tbldata.appendChild(item);
