Hiding a table row is fine, just set document.getElementById(‘theRow’).style.display = ‘none’
When you’re trying to show it though, it can get confusing – for it to display properly, you’ve to set display=’table-row’ for Firefox and display=’block’ for IE.
The solution? Set display=” and the display property for the element gets set to its default (‘table-row’ for FF and ‘block’ for Explorer).

that’s bloody cool! I’ve had to do that many times in the past, and each time, I did a browser-check.
thanks!

I’ve been trying to solve this for two days. Your solution worked perfect to turn a table on and off and an iframe within a table.

For anyone who is scratching their heads wonder why this works for everyone else and not them…. make sure you do not have a CSS display property on the row in question. Since my row was to be hidden by default, I had a CSS snippet of:
tr.hide {display:none}
For whatever reason, this defeats the blank-string-default method mentioned here (i.e. it works with an explicit “table-row”, or, poorly, with “block”, but refuses to show up again with a style.display of “”). If I do the hiding when the row is created in JS instead, ala:
tr.style.display=”none”;
the method works fine.

Thanks! This helped me squash an IE error I was getting when adding table rows with jQuery. Setting it to ‘table-row’ was working great in FF but not in IE.
