Creating a dynamically resizing column in a CSS/HTML table based on the input element's text value

I am encountering an issue with a React table (Using AntD), where I want cells in a specific column to render text inputs. The problem arises when the td element only contains text, as the HTML table automatically adjusts the width of the column based on the longest value in the table. However, when an input element is rendered, the auto-width feature does not function properly. I do not wish to set a fixed width for the column using pixels or percentages; rather, I would like the column with the inputs to dynamically adjust its width based on the longest value within the cells.

Here is the code:

This is a screenshot:

Another example can be seen here:

In the first example, it appears almost perfect... However, in the second example, there is too much space in the first column and the second column adjusts perfectly based on the data or header.

Is there a way for a td element to recognize the width of an input element and automatically adjust the width of the column in the table? Or is there any workaround available?

Answer №1

Is it possible for a td element to adjust its width based on the width of an input element within it?

It seems that the input element itself does not determine its own width. Therefore, the table cannot automatically adjust its column width because the input does not have a fixed width either. You can find more information on this topic by visiting these answers.

Answer №2

Upon exploring various options, it is evident that achieving a scenario like this purely with CSS alone may not be feasible in a concise manner.

However, I have devised a workaround that functions almost flawlessly by analyzing each change, calculating the string length, and adjusting the style using `ch` instead of traditional units like `px` or `%` to modify the `width` of the input field.

In addition, I have implemented a configuration where the style settings are applied to all inputs within the same column, setting a `min-width` of `100%`.

For visual reference, refer to this example: https://i.sstatic.net/189VE.gif

By utilizing `react`, I have engineered a custom hook to streamline event manipulation and maintain centralized control over the process.
