>In Excel, is there a way to avoid a word to wrap on the next line. I have a row of headers and some of them are having only one word but since there is not enough space, the last letter of the word is wrapped and this doesn't look too good.

1. Highlight the column in question
2. Home->Format->Autofit Column Width

You can also double click the column header border.

It seems like you have to do this after the text is changed.
