Row one in my table I want to make as titles that are permanently in row one.

I have frozen the panes so that row one is fixed in place when scrolling down and up. But the data in row one is not frozen.

If I order a column alphabetically the data in row one is reordered with it and so my titles can end up anywhere in the document. How do I fix or freeze row 1 and its data to stay fixed on top?
