element ui 表格 ：width

根据引用中提供的信息，Element UI的表格组件可以通过遍历tableData和表头来找出每一列中最长的字符，并根据该最长字符计算出最小宽度。具体的步骤如下：
1. 使用遍历方法遍历tableData和表头，找出每一列中的最长字符。
2. 创建一个span标签用于计算最长字符所占的宽度，通过offsetWidth属性获取到该宽度。
3. 将获取到的最长字符的宽度设置为列的min-width属性，这样可以确保表格在渲染过程中宽度和高度的稳定性。
4. 在组件渲染前计算出最小宽度，避免表格渲染过程中宽度高度不稳定的情况。

根据你提供的代码示例，可以看出设置了每一列的宽度为"50px"，这种情况下宽度不会自动计算。如果希望实现自动计算宽度，需要将width属性设为"auto"或不设置宽度属性，默

element ui表格抖动

element ui表格抖动的原因是因为无论是显示列还是隐藏列，vue都需要重新计算单元格的高度和宽度，然后再重新渲染到页面上。因为这个过程被直接反馈到了页面上，所以导致了table发生闪烁。解决方法是使用element中的dolayout函数。具体实现方法如下：

<template>
  <el-table
    :data="tableData"
    style="width: 100%"
    :key="tableKey"

element ui表格宽度

您可以通过设置 `width` 属性来控制 Element UI 表格的宽度。具体方法如下：

1. 在 `<el-table>` 标签中添加 `width` 属性，例如：`<el-table :data="tableData" width="100%">`，这样表格的宽度就会被设置为父容器的 100%。

2. 如果您想设置表格的固定宽度，可以使用 `:style="{width: '固定宽度'}"` 来进行设置，例如：`<el-table :data="tableData" :style="{width: '500px'}">`，这样表格的宽度就会被设置为 500px。

另外，您还可以通过设置表格的 `min-width` 和 `max-width` 属性来控制表格的最小和最大宽度。例如：`<el-table :data="tableData" :style="{minWidth: '300px', maxWidth: '800px'}">`，这样表格的宽度就会在 300px 和 800px 之间变化。
