How to Set Maximum Width and Truncate Overflowing Data in BootstrapTable

When working with data tables in web projects, especially using Bootstrap, you might often face a common challenge: how can you control the maximum width of a column and truncate data that exceeds this width? This is particularly true in scenarios where you may have lengthy descriptions in a given field, making the table difficult to read and navigate.

In this guide, we'll explore a straightforward solution to effectively manage column widths in a BootstrapTable within an ASP.NET Web Forms project. We will examine how to use CSS to not only limit the width of the column but also to truncate overflowing text elegantly.

Setting Up Your BootstrapTable

Before diving into the solution, let's take a look at a typical BootstrapTable setup. For instance:

Here, the Description field is particularly prone to long entries that can cause layout problems. Below, we discuss how to tackle this.

Step 1: Truncating with CSS

To ensure that the content of the Description field does not exceed one line, we can apply some specific CSS rules. Here’s a simple solution:

Single Line Truncation

To truncate the content to a single line, use the following CSS:

This will limit the text to a single line and if the text exceeds the available space, it will be truncated with an ellipsis (...).

Multi-Line Truncation (If Needed)

If you wish to allow for a few lines of text before truncation, you can modify the CSS like this:

The -webkit-line-clamp property allows you to specify the number of lines you want the text to display before truncation occurs.

Step 2: Applying CSS to the Table

In your case, you can apply the ellipses class to the Description column. If the content is simple text, you might want to wrap the description content in paragraph tags like so:

This implementation ensures that description text wraps appropriately and remains visually organized.

Conclusion

By combining CSS properties like overflow, white-space, and text-overflow, you can effectively control how BootstrapTable displays data in your ASP.NET projects. Not only does this improve the readability and usability of your tables, but it also enhances the overall user experience.

Feel free to experiment with the provided CSS examples and adjust them according to your specific design needs. If you encounter any challenges, consider revisiting how you've applied the classes and HTML structure.

Happy coding!
