I am working on a paper using the `IEEEtran` template in LyX.

I have run into a problem: While the contents (in this case, a table) of the `figure` float are centered, the caption is aligned to the left (see screenshot below). How can I center the caption as well?

This is generated by the following LyX document:

What I've tried:

1. Center the table (the table is centered)
2. Center all the contents in the float (only the table is centered)
3. Select the caption and center it (no effect)

Technical details:

* LyX 2.0.5.1
* Mac OS X 10.7.5 (Lion)
* All centering was performed by `Right Click`>`Paragraph Settings`>`Align: Center`
