Unfortunately, there is no such topic in the documentation. In general, you can use all the QCSS properties that supports by regular Qt table - QTableView and etc. For other customization, i'd suggest using the grid's API, although many grid settings can be obtained through QCSS, since in the next major update we will no longer expand QCSS support, and customization will be operated through Qt styles based on Adobe HD or Figma design files.
