I am beginner web developer. I make my first crud in Laravel 8 and Vue. I use this component t in my project: https://www.npmjs.com/package/vuejs-datatable
I have this code:
DataTable.vue:
<template>
<div>

<div class="col-3">
<div class="input-group">
<input
v-model="search"

type="text"
>
<div class="input-group-append">
<button class="btn btn-primary" type="button" @click.prevent="handleSearch">
<font-awesome-icon icon="fas fa-search" />
</button>
</div>
</div>
</div>
<div class="col-2">
<div class="input-group">
<label for="pageOption" class="mt-2 mr-2">Na stronie</label>
<select class="form-control" v-model="perPage" @change="handlePerPage" id="pageOption">
<option v-for="page in pageOptions" :key="page" :value="page">{{ page }}</option>
</select>
</div>
</div>
</div>
<table class="table table-hover">

This code work fine.
I have 2 problems:
I would like the column headers in the table to be taken from: headers - currently these are the column names from the database (ie: columns).
I would like to add a link to edit and delete a record. I have created methods: editLink (), deleteNote (). How can I add them to my table? I would like them to be visible next to the "name" column
How can I make it?
Please help me :)
CodePudding user response：
For the problem #1. I would do it this way. Merge the columns and the headers as one Object, ex: where the key will be the column name (Important: don't forget to register the headers prop).
<data-table
:fetch-url="datatTableUrl"
:headers="{'name': 'nazwa','email': 'adres email','id': 'ID' , 'created_at': 'utworzono'}"
></data-table>
In the DataTable:
<th v-for="(column, label) in headers" :key="column" @click="sortByColumn(column)" class="table-head">
{{ label | columnHead }}
<span v-if="column === sortedColumn">
<font-awesome-icon v-if="order === 'asc' " icon="fas fa-angle-up" />
<font-awesome-icon v-else icon="fas fa-angle-down" />
</span>
</th>
For the Second problem #2 (Not very clear), Better to move these functions to the DataTable and add the actions as a new column, short example:
<td><button @click="editLink(key1)">Edit link or some fa fa icon</button></td>
Add as prop in the DataTable:
props: {
fetchUrl: {type: String, required: true},
columns: {type: Array, required: true},
headers: {type: Object, required: true} //<-- This
},
