DocBook supports both the CALS table model and the HTML table model:
[Tables]
; UseCALSModel = No (HTML default) or Yes (XML default)
UseCALSModel = Yes
; UseInformaltableTag = No (default) or Yes (use when there is no
; table caption)
UseInformaltableTag = Yes
; InternalTableCaption = Yes (default) or No (put outside table)
InternalTableCaption = No
; TableCaptionTag = tag for internal table captions, default "caption"
TableCaptionTag = caption
