HTML Tables

 

Defining an HTML Table

An HTML table is defined with the <table> tag.

Each table row is defined with the <tr> tag. A table header is defined with the <th> tag. By default, table headings are bold and centered. A table data/cell is defined with the <td> tag.

<table style="width:100%">
  <tr>
    <th>Firstname</th>
    <th>Lastname</th>
    <th>Age</th>
  </tr>
  <tr>
    <td>Jill</td>
    <td>Smith</td>
    <td>50</td>
  </tr>
  <tr>
    <td>Eve</td>
    <td>Jackson</td>
    <td>94</td>
  </tr>
</table>

HTML Table - Adding a Border

If you do not specify a border for the table, it will be displayed without borders.
A border is set using the CSS border property:

table, th, td {
  border: 1px solid black;
}

HTML Table - Collapsed Borders

If you want the borders to collapse into one border, add the CSS border-collapse property:

table, th, td {
  border: 1px solid black;
  border-collapse: collapse;
}

HTML Table - Adding Cell Padding

Cell padding specifies the space between the cell content and its borders.
If you do not specify a padding, the table cells will be displayed without padding.
To set the padding, use the CSS padding property:

th, td {
  padding: 15px;
}

HTML Table - Left-align Headings

By default, table headings are bold and centered.
To left-align the table headings, use the CSS text-align property:

th {
  text-align: left;
}

HTML Table - Adding Border Spacing

Border spacing specifies the space between the cells.
To set the border spacing for a table, use the CSS border-spacing property:

table {
  border-spacing: 5px;
}

HTML Table - Cells that Span Many Columns

To make a cell span more than one column, use the colspan attribute:

<table style="width:100%">
  <tr>
    <th>Name</th>
    <th colspan="2">Telephone</th>
  </tr>
  <tr>
    <td>Sisu</td>
    <td>00000000</td>
    <td>00000000</td>
  </tr>
</table>

HTML Table - Cells that Span Many Rows

To make a cell span more than one row, use the rowspan attribute:

<table style="width:100%">
  <tr>
    <th>Name:</th>
    <td>Sisu</td>
  </tr>
  <tr>
    <th rowspan="2">Telephone:</th>
    <td>000000000</td>
  </tr>
  <tr>
    <td>0000000000</td>
  </tr>
</table>

HTML Table - Adding a Caption

To add a caption to a table, use the <caption> tag:

<table style="width:100%">
  <caption>Monthly savings</caption>
  <tr>
    <th>Month</th>
    <th>Savings</th>
  </tr>
  <tr>
    <td>January</td>
    <td>RS100</td>
  </tr>
  <tr>
    <td>February</td>
    <td>RS50</td>
  </tr>
</table>

A Special Style for One Table

To define a special style for a special table, add an id attribute to the table:

<table id="t01">
  <tr>
    <th>Firstname</th>
    <th>Lastname</th>
    <th>Age</th>
  </tr>
  <tr>
    <td>Eve</td>
    <td>Jackson</td>
    <td>94</td>
  </tr>
</table>

table#t01 {
  width: 100%;
  background-color: #f1f1c1;
}

table#t01 tr:nth-child(even) {
  background-color: #eee;
}
table#t01 tr:nth-child(odd) {
  background-color: #fff;
}
table#t01 th {
  color: white;
  background-color: black;
}
