Just listen with watch and copy it. Pay attention to checkList and check here

CheckList: represents the default selection of your multi-check boxes. If I don't write it, I will not select all of them by default.

Check: this should be written in the same way as label in lists, which is used to judge.

Watch: {checkList (newVal) {if (newVal) {var arr = this.check.filter (I = > newVal.indexOf (I)

{if (arr.indexOf (i.label)! =-1) {i.ispass = false} else {i.ispass = true}, so much for "vue elementUI table controls how hidden corresponding columns are displayed". Thank you for your reading.
