In web development, in order to improve the user experience, we often beautify and optimize tables. Among them, the color-changing effect of alternate rows in a table is a common and simple operation, which can make the table more tidy and beautiful. This article will introduce how to use JQuery to achieve the color-changing effect of alternate rows in tables, and attach specific code examples.

$(document).ready(function() {
  $("#data-table tr:odd").css("background-color", "#f2f2f2");

Summary: Through the introduction of this article, we have learned how to use JQuery to achieve the interlaced color changing effect of tables. This is a simple and practical function that can improve user experience in actual development and add beauty and comfort to the page. I hope this article can be helpful to you, and you are welcome to try to apply this effect in actual projects to make the page more vivid and interactive!
