Page Header Alignment in Numbers
Hello, Numbers gurus. I'm having trouble aligning text in a page header. By default, text entered in the center portion of the page header is centered. So far, so good. However, when I add a second line that line is left-aligned directly below the left edge of the first line of text. I want the second line also to be centered but no matter what text I select, the alignment icons in the Text inspector are grayed out. See the screenshot below. Something similar happens when I add more than one line of text in the righthand portion of the page header; only the first line is right-aligned. Help!
