el-table去除表格表頭多選框或者更換為文字

1、多選框那一列加label-class-name

 <el-table-column type="selection" width="55"  label-class-name="DisabledSelection" :reserve-selection="true"></el-table-column>

2、style加樣式

/*表格全選框去除空框*/
.el-table >>> .DisabledSelection .cell .el-checkbox__inner {
  display: none;
  position: relative;
}
/*表格全選框改為：選擇*/
.el-table >>> .DisabledSelection .cell:before {
  content: "選擇";
  position: absolute;
  left: 7px;
}
