CSS provides a number of properties that allow you to style tables in your HTML documents. Here are some examples:

1. border-collapse: This property allows you to specify whether the borders of table cells should be collapsed into a single border or separated into individual borders. The possible values are collapse and separate.

table {
    border-collapse: collapse;
}

2. border-spacing: This property allows you to specify the space between the borders of adjacent table cells. You can specify the space using either absolute or relative units.

table {
    border-spacing: 10px;
}

3. caption-side: This property allows you to specify the position of the table caption. The possible values are top, bottom, left, and right.

table {
    caption-side: top;
}

4. empty-cells: This property allows you to specify whether cells with no content should be displayed with a border and background. The possible values are show and hide.

td {
    empty-cells: show;
}

5. table-layout: This property allows you to specify the algorithm that is used to lay out the table. The possible values are auto and fixed.

table {
    table-layout: fixed;
}

These are just a few examples of the properties that you can use to style tables in CSS. There are many other properties available as well. It’s a good idea to familiarize yourself with all of these properties so that you can choose the most appropriate ones for your needs.
