This article explores creating dynamic tables using Alpine JS, a lightweight JavaScript framework. We'll break down the process into three sections: header, body, and footer, focusing on both basic and complex scenarios.

Setting Up:

1. HTML Structure: We begin with a basic HTML element () with the x-data directive attached. This directive binds reactive data to the element.
2. JavaScript Data: We define an empty JavaScript object (data) outside the HTML to hold our table data.

The initial code is below:


Header

• We use the thead element for the header.
• The x-for directive iterates over table.customHeader data, creating rows and columns dynamically.
• Complex headers can leverage colspan and rowspan attributes (defined in col.attr) to merge cells.
• Content within each cell is displayed using x-html and bound to the col.title property.

let data = {
  table: {
      customHeader: [
          [
              { title: 'City', attr: { rowspan: 2 }, class: 'border-r border-t' },
              { title: 'Clothes', attr: { colspan: 3 }, class: 'border-r border-t' },
              { title: 'Accessories', attr: { colspan: 2 }, class: 'border-t' }
          ],
          [
              { title: 'Trousers', class: 'border-r' },
              { title: 'Skirts', class: 'border-r' },
              { title: 'Dresses', class: 'border-r' },
              { title: 'Bracelets', class: 'border-r' },
              { title: 'Rings' },
          ]
      ],
  }
}

Body

• The tbody element holds the table's data rows.
• We iterate through table.data using x-for.
• Each row houses cells () populated with data from corresponding object properties using x-text.

  And this is the data we want to show:
  

  data: [
      { "city": "Mandalay", "trousers": 79, "skirts": 16, "dresses": 14, "bracelets": 69, "rings": 99 },
      { "city": "George Town", "trousers": 68, "skirts": 24, "dresses": 90, "bracelets": 96, "rings": 48 },
      { "city": "Gent", "trousers": 26, "skirts": 60, "dresses": 67, "bracelets": 5, "rings": 43 },
      { "city": "Mombasa", "trousers": 34, "skirts": 62, "dresses": 18, "bracelets": 75, "rings": 78 },
      { "city": "Lyon", "trousers": 13, "skirts": 33, "dresses": 12, "bracelets": 0, "rings": 17 },
      { "city": "Vancouver", "trousers": 82, "skirts": 91, "dresses": 18, "bracelets": 96, "rings": 72 },
      { "city": "Cairn", "trousers": 64, "skirts": 43, "dresses": 14, "bracelets": 95, "rings": 55 },
  ]
  

  Footer

  • The tfoot element defines the footer.
  • Similar to the header, it uses x-for to iterate through table.customFooter data.
  • However, the footer can display dynamic values by referencing properties within table.footerData using x-html.

  customFooter: [
      [
          { value: 'Total', class: 'font-bold border-r text-center', attr: { rowspan: 2 } },
          { name: 'total-trousers', class: 'text-right border-r' },
          { name: 'total-skirts', class: 'text-right border-r', },
          { name: 'total-dresses', class: 'text-right border-r' },
          { name: 'total-bracelets', class: 'text-right border-r' },
          { name: 'total-rings', class: 'text-right' },
      ],
      [
          { name: 'total-clothes', class: 'text-center border-r', attr: { colspan: 3 } },
          { name: 'total-accessories', class: 'text-center', attr: { colspan: 2 } },
      ],
  ],
  

  Example Data:

  We demonstrate the table's functionality with sample data containing city names and various clothing items.

  Additional Notes:

  • Styling is achieved using CSS classes defined within the col.class and data.class properties.
