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.
- HTML table
<table> - table row
<tr> - table header
<th> - table data/cell
<td>
Note: The <td> elements are the data containers of the table.
They can contain all sorts of HTML elements; text, images, lists, other tables, etc.
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;
}
Remember to define borders for both the table and the table cells.
HTML Table - Collapsed Borders 设置表格的边框是否被合并为一个单一的边框,还是象在标准的 HTML 中那样分开显示对应的脚本特性（即由原来的双框线变成单框线）
table, th, td {
border: 1px solid black;
border-collapse: collapse;
}
HTML Table - Adding Cell Padding 限定内容与边框的距离
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;
}
Note: If the table has collapsed borders, border-spacing has no effect.
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>Bill Gates</td>
<td>55577854</td>
<td>55577855</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>Bill Gates</td>
</tr>
<tr>
<th rowspan="2">Telephone:</th>
<td>55577854</td>
</tr>
<tr>
<td>55577855</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>$100</td>
</tr>
<tr>
<td>February</td>
<td>$50</td>
</tr>
</table>
Note: The <caption> tag must be inserted immediately after the <table> tag.
A Special Style for One Table 定义表格的背景色和填充色等
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>
Now you can define a special style for this table:
table#t01 {
width: 100%;
background-color: #f1f1c1;
}
<!DOCTYPE html>
<html>
<head>
<style>
table, th, td {
border: 1px solid black;
border-collapse: collapse;
}
th, td {
padding: 15px;
text-align: left;
}
table#t01 {
width: 100%;
background-color: #f1f1c1;
}
</style>
</head>
<body>
<h2>Styling Tables</h2>
<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>
<tr>
<td>John</td>
<td>Doe</td>
<td>80</td>
</tr>
</table>
<br>
<table id="t01">
<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>
<tr>
<td>John</td>
<td>Doe</td>
<td>80</td>
</tr>
</table>
</body>
</html>
And add more styles:
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;
}
