Column resizing in Vue Treegrid component
11 Jun 202413 minutes to read
Column width can be resized by clicking and dragging the right edge of the column header. While dragging, the width of the respective column will be resized immediately. Each column can be auto resized by double-clicking the right edge of the column header to fit the width of that column based on the widest cell content. To enable column resize, set the allowResizing
property to true.
To use the column resize, inject Resize
module in the treegrid.
<template>
<div id="app">
<ejs-treegrid :dataSource="data" childMapping='subtasks' :treeColumnIndex='1' :allowResizing='true' height='315px'>
<e-columns>
<e-column field='taskID' headerText='Task ID' width=90 textAlign='Right'></e-column>
<e-column field='taskName' headerText='Task Name' width=180></e-column>
<e-column field='startDate' headerText='Start Date' width=90 format="yMd" textAlign='Right'></e-column>
<e-column field='duration' headerText='Duration' width=80 textAlign='Right'></e-column>
</e-columns>
</ejs-treegrid>

<script setup>
import { provide } from "vue";
import { TreeGridComponent as EjsTreegrid, Resize, ColumnDirective as EColumn, ColumnsDirective as EColumns } from "@syncfusion/ej2-vue-treegrid";
import { sampleData } from "./datasource.js";
const data = sampleData;
provide('treegrid', [ Resize ]);
</script>

<script>
import { TreeGridComponent, Resize, ColumnDirective, ColumnsDirective } from "@syncfusion/ej2-vue-treegrid";
import { sampleData } from "./datasource.js";
export default {
name: "App",
components: {
"ejs-treegrid":TreeGridComponent,
"e-columns":ColumnsDirective,

- You can disable resizing for a particular column by setting the
columns.allowResizing
to false.- In RTL mode, you can click and drag the left edge of the header cell to resize the column.
Min and max width
Column resize can be restricted between minimum and maximum width by defining the columns->minWidth
and columns->maxWidth
.
In the following sample, minimum and maximum width are defined for Duration
, and Task Name
columns.
<template>
<div id="app">
<ejs-treegrid :dataSource="data" childMapping='subtasks' :treeColumnIndex='1' :allowResizing='true' height='315px'>
<e-columns>
<e-column field='taskID' headerText='Task ID' width=90 textAlign='Right'></e-column>
<e-column field='taskName' headerText='Task Name'minWidth= 170 width=180 maxWidth=250></e-column>
<e-column field='duration' headerText='Duration' minWidth= 50 width=80 maxWidth=150 textAlign='Right'></e-column>
<e-column field='progress' headerText='Progress' width=80 textAlign='Right'></e-column>
</e-columns>
</ejs-treegrid>
</div>
</template>
<script setup>
import { provide } from "vue";
import { TreeGridComponent as EjsTreegrid, Resize, ColumnDirective as EColumn, ColumnsDirective as EColumns } from "@syncfusion/ej2-vue-treegrid";
import { sampleData } from "./datasource.js";
const data = sampleData;
provide('treegrid', [ Resize ]);
</script>
<template>
<div id="app">

Resize stacked column
Stacked columns can be resized by clicking and dragging the right edge of the stacked column header. While dragging, the width of the respective child columns will be resized at the same time. You can disable resize for particular stacked column by setting allowResizing
as false
to its columns.
<template>
<div id="app">
<ejs-treegrid :dataSource="data" childMapping='subtasks' :treeColumnIndex='1' :allowResizing='true' height='260px'>
<e-columns>
<e-column headerText='Order Details' :columns='orderColumns'></e-column>
<e-column headerText='Shipment Details' :columns='shipColumns'></e-column>
</e-columns>
</ejs-treegrid>
</div>
</template>
<script setup>
import { provide } from "vue";
import { TreeGridComponent as EjsTreegrid, Resize, ColumnDirective as EColumn, ColumnsDirective as EColumns } from "@syncfusion/ej2-vue-treegrid";
import { stackedData } from "./datasource.js";
const data = stackedData;
const orderColumns = [
{ field: 'orderID', headerText: 'Order ID', textAlign: 'Right', width: 90 },
{ field: 'orderName', headerText: 'Order Name', textAlign: 'Left', width: 170 },
];
const shipColumns = [
{ field: 'shipMentCategory', headerText: 'Shipment Category', textAlign: 'Left', width: 90 },
{ field: 'shippedDate', headerText: 'Shipped Date', textAlign: 'Right', format: 'yMd', width: 90 }
];
provide('treegrid', [ Resize ]);
