Table “styles” are very badly designed and they aren’t styles at all. They are more like a set of macros triggered after some events, like adding a new row or column. And this repaints the whole table, cancelling your customisation.
If you are satisfied with provided models “as is”, i.e. don’t ever try to apply any user formatting over them, go with them. Note the strong restriction about the impossibility to adapt them to your needs or tastes.
Otherwise design your table yourself manually and copy-paste the occurrence at start of every chapter.
Could you elaborate more on your goal? Do you want a chapter-TOC at start of chapter? Or do you add a kind of “abstract” there? If you use a table only to draw a border around this “abstract”, there is a better and more efficient (performance-wise) way of doing it with styles (and this will alos take care of the bullet).
Don’t forget to mention OS name, exact LO version and save format (because most suggestions are only stable and persistent in .odt).
