Element-ui table sorting defaults to ascending order, and then clicking descending order. How to set the descending order first?

when it comes to the demand of comparison pit, element-ui table sorting defaults to ascending order first, and then clicking descending order. Now it is time to descend the order for the first time, and then click to ascend the order. Looking around, I couldn"t find the interface that element-ui provided to change. And I didn"t find a viable way. Which great god has met or knows how to solve it?


:default-sort = "{prop: 'date', order: 'ascending'}" //descending

sort-orders= "['descending','ascending','descending']"
