[Bug Report] Console error with multiselect table, rowKey and reserve-selection #18084

Open pixagraphic opened 4 years ago

pixagraphic commented 4 years ago

Element UI version

2.12.0

OS/Browsers version

Mac OSx 10.15.1, Firefox 70.0.1

Vue version

2.6.10

Reproduction Link

https://codepen.io/pixagraphic/pen/YzzdweK

Steps to reproduce

Simple create a multiselect table with :reserve-selection:="true" and required rowKey method. (see pen) Console will output an error TypeError: "data is null.

What is Expected?

Expected behaviour would be no console errors.

What is actually happening?

updateExpandRows() in "packages/table/src/store/expand.js" does not check if data is null. Statement if (!data) return; is required before this.states.expandRows = data.slice();
