DOM notes

I've recently been converting one of our tools from a raw html/innerHTML backend to DOM implementation, in order to: 1) Save processing time 2)More easily update and interact with the tool 3) Learn more about the DOM. Here's what I've learned thus far.
*Note* - Lately for time-saving purposes, I have only dealt with mozilla and Internet Explorer, the two market leaders. Therefore, these notes may need to be supplemented. Commment below if you notice any such cases.

** This is missing one important note ("insertCell with Mozilla" below).

** IMPORTANT ** insertCell/insertRow with Mozilla
When using insertCell/insertRow with Mozilla, you must pass an argument. If you don't, it will error, but won't alert you. For example:

To insert a row at the end(default)
Pass -1 as the argument.
tbody.insertRow(-1)

To insert a row at the beginning of the rows
Pass 0 as the argument.
tbody.insertRow(-1)

Mozilla documentation on insertRow
