Hello rsimm.

Thank you for contacting us!

As I understand you want to align the text within igGrid headers vertically. I have created a sample for you in order to show you this approach. As you can see from the sample I am overriding the css class .ig-iggrid-headertext with:

.ui-iggrid-headertext {
            display: inline-block;
            vertical-align: middle;
            white-space: normal;
        }

Online sample:

I hope that you will find the sample helpful.
