Locking Table Header and First Column with JavaScript
Freezing table panes is a common requirement in spreadsheets and tables, allowing users to scroll without losing context by locking specific rows or columns. While CSS lacks the capability to lock table elements, JavaScript offers a solution.
JavaScript Solution
To achieve this functionality, a JavaScript plugin such as fixed-table-rows-cols can be employed. This open-source plugin provides a simple solution to create scrollable tables with fixed table headers and columns.
The plugin converts a well-formatted HTML table into a scrollable table with fixed columns and headers. Its usage is straightforward, as demonstrated below:
<code class="javascript">$('#myTable').fxdHdrCol({
fixedCols : 3, /* 3 fixed columns */
width : "100%", /* set the width of the container (fixed or percentage)*/
height : 500 /* set the height of the container */
});</code>
The fixedCols option specifies the number of columns to lock, while the width and height options control the container's dimensions. To lock the first row and first column, set fixedCols to 1.
By utilizing this plugin, developers can easily implement table locking functionality with a few lines of code, ensuring that users can navigate through large datasets without losing sight of critical information.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
