version 2.3.9 has fixed this issue. For more information, please see update log

has the blogger solved it? With the same problem? I didn't find the reason. Is there something wrong with some dependency?

I also encountered this problem. I don't know how to solve

I also encountered this problem. The landlord solved no

final solution:
packget.json 's "element-ui": "^ 2.3.7", change it to "element-ui": "^ 2.3.9", and re-install.

temporary solution at that time:

<el-table
@cell-mouse-enter = "cellMouseEnter">

cellMouseEnter(row, column, cell, event){
        console.log(arguments);
        // text-overflow, tooltip --->//
        var cellChild = event.target.querySelector('.cell');
        // console.log(cellChild.innerHTML==='');
        if(''===cellChild.innerHTML){
          cellChild.innerHTML = '&nbsp';
        }
        // range.cloneRange()
        // range.insertNode();
        // var range = document.createRange();
        // range.setStart(cellChild, 0);
        // range.setEnd(cellChild, 1);
        
      },
