1. Basic Methods of Styling Tables with CSS

To style a table, we first need to understand how to select table elements and then style them using CSS properties. The following are some commonly used methods and properties:

1.1 Selecting Table Elements

In CSS, we can use tag selectors, class selectors, or ID selectors to select table elements. For example, the table selector can be used to select all tables, and the th selector can be used to select table header cells.

/* Select all tables */
table {
/* Style settings */
}

/* Select table header cells */
th {
/* Style settings */
}

1.2 Table Border Styles

By setting the border property, we can add border styles to tables and cells. We can set the border width, color, and style.

/* Set the table border style */
table {
border: 1px solid #000;
}

/* Set the cell border style */
td {
border: 1px solid #000;
}

1.3 Table Background Color

By setting the background-color property, we can add background colors to tables and cells.

/* Set the table background color */ 
table { 
background-color: #f5f5f5; 
} 

/* Set the cell background color */ 
td { 
background-color: #fff; 
} 

1.4 Table Font Style

By setting the font-family, font-size, and color properties, we can change the font, size, and color of text in a table.

/* Set the table font style */ 
table { 
font-family: Arial, sans-serif; 
font-size: 12px; 
color: #333; 
} 

/* Set the cell font style */ 
td { 
font-family: Arial, sans-serif; 
font-size: 12px; 
color: #333; 
} 

2. Styling Table Rows and Columns

In addition to styling the entire table, we can also style table rows and columns to achieve different effects.

2.1 Styling Table Rows

We can use the pseudo-class selector :nth-child() to select specific rows in a table and then style them. Here are some examples:

/* Set the background color of the even-numbered lines to gray */ 
tr:nth-child(even) { 
background-color: #f5f5f5; 
}

/* Set the font of the first row to bold */
tr:first-child {
font-weight: bold;
}

/* Set the border style of the last row */
tr:last-child {
border: 1px solid #000;
}

2.2 Styling Table Columns

To style table columns, we first need to add <col> elements to the table and use CSS selectors to select them. Here are some examples:

<table> 
<colgroup> 
<col span="1" style="background-color: #f00;"> 
<col span="1" style="background-color: #0f0;"> 
<col span="1" style="background-color: #00f;"> 
</colgroup> 
<thead> 
<tr> 
<th>Column 1</th> 
<th>Column 2</th> 
<th>Column 3</th> 
</tr> 
</thead> 
<tbody> 
<tr> 
<td>Data 1</td> 
<td>Data 2</td> 
<td>Data 3</td> 
</tr> </tbody> 
</table> 

In the example above, we use the <colgroup> element to define three columns in the table and set different background colors for each column.

3. Practical Application of Table Styling

Table styling is very common in web design. The following examples demonstrate some common techniques for styling tables using CSS:

3.1 Alternating Background Colors for Odd and Even Rows

/* Set alternating background colors for odd and even rows */ 
tr:nth-child(even) {
background-color: #f5f5f5; 
} 

This setting makes the table easier to read and improves its aesthetics.

3.2 Hover Effects

/* Hover Effects */ 
tr:hover { 
background-color: #d9d9d9; 
} 

When the mouse hovers over a table row, the row’s background color can be changed to remind the user that the row is selected or in focus.

3.3 Zebra Stripe Effects

/* Zebra Stripe Effects */ 
tr:nth-child(odd) { 
background-color: #f5f5f5; 
} 

The zebra stripe effect can make tables clearer and easier to read, and can reduce eye strain.

3.4 Fixed Table Header

/* Fixed Table Header */
thead {
position: sticky;
top: 0;
background-color: #fff;
}

When a table is long, fixing the header to the top of the page makes it easier for users to view the table contents and compare data.
