How the el-table of Element responds to keyboard events

Hey guys, I want to use tapping spaces to implement QuickLook in el-table .
idea is to listen for their own keyboard events and prevent them from continuing to spread, thus killing the keyboard events of default keystrokes spaces , scroll bars page flipping .
but I don"t know how to use el-table to listen for keyboard events.
how to do this?
