As you can see from the overall framework code, element-ui has already realized the fixed head . Find this fixedHeader and find that if it is set to false
directly in the global setting file , it means that the head is not fixed; if it is changed to true, it means the head
fixed.
After the above changes, the head can be fixed.

This may be because the z-index is changed after the head is fixed, and then there is a problem with the corresponding display. The
solution:
add it to the triggered el-dialog :append-to-body="true". The specific official explanation is as follows:
Then the display can be normal! !
