Vxe UI vue vxe-table grid 如何滚动、定位到指定行或列

article 2024/10/24 17:26:53

Vxe UI vue vxe-table vxe-grid 在表格中有时候需要对数据会列进行操作。可以会定位到某一行或某一列，vxe-table 中提供了丰富的函数式 API，可以轻松对行与列进行各种的灵活的操作。

定位到指定行与列

通过调用 scrollColumn(columnOrField) 方法，参数就是当前列的字段名
通过调用 scrollRow(row, column?: columnOrField) 方法，参数就是当前行对象
第二个参数是可选的，支持同时定位到指定列

在这里插入图片描述

调用该方法之后会始终显示在表格的可视区之内。

<template>
  <div>
    <div>
      <vxe-button @click="scrollToCol('attr1')">定位 Attr1 列</vxe-button>
      <vxe-button @click="scrollToCol('attr4')">定位 Attr4 列</vxe-button>
      <vxe-button @click="scrollToCol('attr8')">定位 Attr8 列</vxe-button>
    </div>
    <div>
      <vxe-button @click="scrollToRow(gridOptions.data[3])">定位第4行</vxe-button>
      <vxe-button @click="scrollToRow(gridOptions.data[9])">定位第10行</vxe-button>
      <vxe-button @click="scrollToRow(gridOptions.data[15])">定位第16行</vxe-button>
    </div>
    <vxe-grid ref="gridRef" v-bind="gridOptions"></vxe-grid>
  </div>
</template>
