Anyone who knows me knows I (ab)use elog a lot.   And this one is another of a long list of cheats and work arounds rather than modifying the code properly.

In summary mode, the top row are titles, and if they are long, they will dominate the width of that column.  Similarly if they are short, if entries under that title are either non-existant or even shorter.  Sometimes entries below the title will dominate, e.g. entries under "Date" title.

I assume your entries under the title in question are things like more than one word, such that they get split into two rows within that cell.  Sometimes that can look very untidy.  However, if you want the column wider than the title is given, you can pad out the title with " " (without the "").  Either on both sides for a centred title, or on the right for left justified.  Or between words if the title has more than one.  (Sorry for this edit, I hit submit button rather than preview).
