Usage

Basic Usage

The minimum configuration usage is like following:

<DataTable :headers="headers" v-model="users" />

<script>
import DataTable from "@2alheure/vue-datatable";

export default {
  components: {
    DataTable
  },
  data() {
    return {
      headers: [
        { html: "ID", linkTo: "id" },
        { html: "Gender", linkTo: "gender" },
        { html: "First Name", linkTo: "first_name" },
        { html: "Last Name", linkTo: "last_name" },
        { html: "Email", linkTo: "email" },
        { html: "IP Address", linkTo: "ip_address" }
      ],
      users: [
        {
          "id": 1,
          "first_name": "<b>Virginie</b>",
          "last_name": "Merrin",
          "email": "vmerrin0@howstuffworks.com",
          "gender": "Female",
          "ip_address": "86.87.125.205"
        },
        {
          "id": 2,
          "first_name": "<b>Mariana</b>",
          "last_name": "Dorgan",
          "email": "mdorgan1@indiegogo.com",
          "gender": "Female",
          "ip_address": "188.236.23.74"
        },
        {
          "id": 3,
          "first_name": "<b>Karalee</b>",
          "last_name": "Dod",
          "email": "kdod2@va.gov",
          "gender": "Female",
          "ip_address": "82.75.65.131"
        }
      ]      
    }
  }
};
</script>

Please note the v-model directive. The users object will be modified by the component. If needed, think of making a copy of your data, and not passing it directly to the component.
Please note that in this configuration, the order of the headers prop does matters. Columns will be displayed in that order.
headers.linkTo property must correspond to a property of the v-model linked object.

Template / Slot usage

You can also be more verbous and write your own rows' templates.
Here is an example, corresponding to the one above:

<DataTable v-model="users">
  <template #thead>
    <tr>
      <th>ID</th>
      <th>Gender</th>
      <th>First Name</th>
      <th>Last Name</th>
      <th>Email</th>
      <th>IP Address</th>
    </tr>
  </template>

  <tr v-for="(user, index) in users" :key="index">
  <td
      v-for="(header, headerIndex) in headers"
      :key="index+'-'+headerIndex"
      v-html="user[header.linkTo]"
  ></td>
  </tr>
</DataTable>

<script>
import DataTable from "@2alheure/vue-datatable";

export default {
  components: {
    DataTable
  },
  data() {
    return {
      users: [
        // Same as above
      ]
    }
};
</script>

The <template #thead> describes the content of the <thead> tag of the table.
The rest stands for the <tbody> tag. You can also specify the <template #default> tag but I am lazy so I don't (😜).
As the templates renders according to users and users is used in the v-model, it re-renders automatically with rows that need to be printed.
This will produce the same result as the previous example, except that you won't have the column ordering. To do so, you can use the data-order-by attribute on the header:

  <template #thead>
    <tr>
      <th data-order-by="id">ID</th>
      <th data-order-by="gender">Gender</th>
      <th data-order-by="first_name">First Name</th>
      <th data-order-by="last_name">Last Name</th>
      <th data-order-by="email">Email</th>
      <th data-order-by="ip_address">IP Address</th>
    </tr>
  </template>

About the headers prop

The headers prop is mandatory when you use the DataTable without specifying the <template #thead>.
It must be an array of objects, each one containing two keys:

• html: This will be the HTML content of the <th> tag
• linkTo: This is the property of the corresponding key in the v-model linked prop for the column.

About translations

A translation can be a string, corresponding to one of the following values:

• de: german
• en: english (default value)
• es: spanish
• fr: french

You can also provide an object, which will replace the default translation sentences.
The translation object looks like following (which is the default one):

{
  "noContent": "There is nothing to print.",
  "showing": "Showing lines {0} to {1} of {2}.",
  "search": "Search"
}

If you provide an object, it must match this template, and all keys are required.
