Easy to use, does the job well

I used this to convert text into two horizontal columns on my page – it couldn’t have been easier. It is also possible to add a border (as pointed out in the support thread) by adding something like this in your CSS editor (no need to modify original theme style.css)

.one_half {
width: 45% !important;
margin-right: 2% !important;
border-style: solid !important;
border-width: medium !important;
border-color: #808080 !important;
}

You can find the CSS for the different column widths under the Plugin readme.txt
