1. Borders and Spacing:
Use border properties to define the border style, width, and color. Adjust border-spacing to control the space between cells.

table {
border-collapse: collapse;
width: 100%;
}

th, td {
border: 1px solid #dddddd;
text-align: left;
padding: 8px;
}

2. Background and Text Color:
Customize the table’s background and text color to enhance readability.

th {
background-color: #f2f2f2;
}

tr:nth-child(even) {
background-color: #f9f9f9;
}

3. Responsive Tables:

In the era of diverse screen sizes, it’s crucial to create tables that adapt to different devices. CSS offers the overflow-x property to enable horizontal scrolling on smaller screens.

table {
overflow-x: auto;
display: block;
}

4. Pseudo-Classes and Pseudo-Elements:

Leverage pseudo-classes like :hover to add interactivity or pseudo-elements like ::before and ::after for additional styling elements.

tr:hover {
background-color: #e0e0e0;
}
td::before {
content: "Data: ";
font-weight: bold;
}

5. Colspan and Rowspan:

The colspan attribute allows a cell to span multiple columns, while rowspan lets a cell span multiple rows. CSS can be used to fine-tune the appearance of such merged cells.

td[colspan="2"] {
background-color: #d1f0ff;
}
