Images used in tables are usually decorative icons so they need either:
# a minimal alt text (<code>|alt= ...</code>);
# to be unlinked and empty alt text (<code>|link=|alt=</code>).
For details and explanations concerning images that are not decorative, see [[WP:ALT]].
Note that images in headers can by particularly annoying for [[screen reader]] users if they are badly handled. If the image doesn't comply to the criterions above, the filename will be part of the header title. The filename will be read aloud in every cell under the header containing the icon.
