HTML tables can be sized using the width and height attributes, which specify the dimensions of the table in pixels, percentages, or relative units like em or rem.

Setting Table Width

Pixels:
HTML
```
<table width="400">
  </table>
```
Percentages:
HTML
```
<table width="80%">
  </table>
```
Relative Units:
HTML
```
<table width="20em">
  </table>
```

Setting Table Height

Pixels:
HTML
```
<table height="300">
  </table>
```
Percentages:
HTML
```
<table height="60%">
  </table>
```
Use code with caution.
Relative Units:
HTML
```
<table height="15em">
  </table>
```

Example with Different Sizes

HTML

<table>
  <tr>
    <th>Product</th>
    <th>Price</th>
  </tr>
  <tr>
    <td>Product A</td>
    <td>$100</td>
  </tr>
  <tr>
    <td>Product B</td>
    <td>$200</td>
  </tr>
</table>

<table width="300" height="200">
  <tr>
    <th>Product</th>
    <th>Price</th>
  </tr>
  <tr>
    <td>Product A</td>
    <td>$100</td>
  </tr>
  <tr>
    <td>Product B</td>
    <td>$200</td>
  </tr>
</table>

Important Notes

Responsive Design: For tables to adapt to different screen sizes, consider using percentages or relative units instead of fixed pixel values.
Overflow: If the content within a table cell exceeds the specified dimensions, it might overflow or be clipped. Use CSS properties like overflow-x and overflow-y to handle this.
Table Layout: The table-layout property can affect how the table is rendered. The default value is auto, which means the table layout is determined by the content. You can also use fixed to specify a fixed table layout, which can improve performance in certain scenarios.

By effectively using the width and height attributes, you can control the dimensions of your HTML tables to fit your specific layout requirements and ensure optimal display across different devices and screen sizes.
