The example in this article describes the method of dynamically modifying the colspan column span of table rows in js. Share it with everyone for your reference. The details are as follows:
<!DOCTYPE html> <html> <head> <script> function setColSpan() { var x=document.getElementById('myTable').rows[0].cells; x[0].colSpan="2"; x[1].colSpan="6"; } </script> </head> <body> <table id="myTable" border="1"> <tr> <td colspan="4">cell 1</td> <td colspan="4">cell 2</td> </tr> <tr> <td>cell 3</td> <td>cell 4</td> <td>cell 5</td> <td>cell 6</td> <td>cell 7</td> <td>cell 8</td> <td>cell 9</td> <td>cell 10</td> </tr> </table> <form> <input type="button" onclick="setColSpan()" value="Change colspan"> </form> </body> </html>
I hope this article will be helpful to everyone’s JavaScript programming design.
