npm install vue3-columns-resizable

🚀 Quick Start

// main.ts or entry file
import { createApp } from 'vue'
import App from './App.vue'

const app = createApp(App)
app.use(vue3ColumnsResizable)
app.mount('#app')

🧩 Usage

You can use the v-columns-resizable directive on either:

<table> — to apply resizing globally

<thead> — to apply resizing only on header

<script setup>
function onColumnResized(event) {
  console.log('Column resized:', event.detail)
  // {
  //   index: number,        // current column index
  //   width: number,        // new width of the current column (px)
  //   nextIndex: number,    // index of the next column
  //   nextWidth: number     // new width of the next column (px)
  // }
}
</script>

<template>
  <table class="resizable-table" v-columns-resizable @column-resized="onColumnResized">
    <thead>
      <tr>
        <th width="50%">Name</th>
        <th width="25%">Age</th>
        <th width="25%">Gender</th>
      </tr>
    </thead>
    <tbody>
      <tr>
        <td>John</td>
        <td>20</td>
        <td>Male</td>
      </tr>
      <tr>
        <td>Emma</td>
        <td>18</td>
        <td>Female</td>
      </tr>
    </tbody>
  </table>
</template>

📡 Events

Event	Description	Payload (event.detail)
column-resized	Emitted during drag when column size changes	{ index, width, nextIndex, nextWidth } – all values in pixels

⚙️ Advanced Notes

• Widths are updated via inline style.width in pixels.

• There is no min-width restriction enforced by default. You may enforce it manually.

• You can listen to column-resized to persist layout changes, e.g., save to localStorage or backend.
