I think you need store the selected rows by yourself, and leverage el-table apis, such as toggleRowSelection, to implement.

Of course I can do it. But you know, any professional tables implemented this behaviour by default.

[njleonzhang]

currently, it is not supported. I will consider to implement.

I have found a workaround for the moment, you can do this
this.$refs.periodDatatable.$children[0].toggleRowSelection(this.data[1])

Selected the first children of the data-table-server because its a wrapper around el-table from element ui, and with this code this.$refs.periodDatatable.$children[0] you can leverage every native function of the EL TABLE component.

It works but i don't know if its the best solution, the best solution would be to add this function in the datatables component directly !

I have been really busy recently, I am afraid I can not implement this feature in short term. PR is welcomed. 😭
