In Confluence 6.6.13, can I control the column width for a set of columns from JQL query?

[Jeff Sydor]

I have a JQL statement that brings back 5 or 6 columns and I use a macro to render it on a page.   The column headings are wrapping in a manner that breaks up words in the middle and assigns a disproportionate amount of the page width to one column which is Jira Text.
