First you need to make sure you are reading the appropiate Apache documentation. DreamHost is running v1.3.27, and you can find the documentation at Apache HTTP Server Version 1.3, specifically the mod_autoindex module.
I visited that directory, and you already have FancyIndexing turned on. With FancyIndexing off, the output is just an HTML unordered list. If you would like icons, you need to upload some and then use the AddIcon directive to set them up.
As for HTMLTable, that option is available in Apache v2.0.23 and later.
