element-ui table and tooltip modify the background color and arrow color

1. Modify the text prompt background of element-ui tooltip:

The first step: (set the class for the tooltip first: popper-class to prevent the styles of other parts from being overwritten, as shown below;)

<el-tooltip popper-class="tps" enterable content="这是提示内容。"placement="bottom">
                              
  <i class="el-icon-warning-outline"></i>
                            
</el-tooltip>

The second step: (The following codes can be selected according to the actual situation;)

.tps.el-tooltip__popper {
      background: red;
    }

// 深色系可以添加一个类 is-dark
.tps.el-tooltip__popper.is-dark {
      background: red;
    }

// 系可以添加一个类 is-light
.tps.el-tooltip__popper.is-light {
      background: red;
    }

 

2. Element-ui tooltip text prompt triangle color modification
    Description: .el-tooltip__popper[x-placement^="direction"] .popper__arrow:after
                 border-direction-color: red
                .el-tooltip__popper[x-placement^="direction" ”].popper__arrow
                border-direction-color: red

The code is as follows: (Note: If there is a background color, please write the transparency separately, as shown below)

.el-tooltip__popper[x-placement^="top"] .popper__arrow:after,
    .el-tooltip__popper[x-placement^="top"] .popper__arrow {
      border-top-color: red;
      opacity: 0.5;
    }

3. Modify the style of show-overfloe-tooltip in el-table

<el-table
        :data="tableData"
        :max-height="'753'"
        :tooltip-effect="'tooltipStyle’”     //重点
      >

        <el-table-column
          prop="replacereason"
          label="更改原因"
          :show-overflow-tooltip="true"
        ></el-table-column>
</el-table>

.is-tooltipStyle {
  background: #fff;
  color: #3759af;
  border: 1px solid rgb(158, 157, 157);
  font-size: 15px;
