js method to get the number of rows and columns of a table_javascript skills

How to use JavaScript to get the number of rows and columns of a table? It’s actually very simple, assuming the following table exists:

<table width="100%" border="1" cellspacing="0" cellpadding="0" id="example_table"> 
  <tr> 
    <td> </td> 
    <td> </td> 
    <td> </td> 
    <td> </td> 
    <td> </td> 
  </tr> 
  <tr> 
    <td> </td> 
    <td> </td> 
    <td> </td> 
    <td> </td> 
    <td> </td> 
  </tr> 
  <tr> 
    <td> </td> 
    <td> </td> 
    <td> </td> 
    <td> </td> 
    <td> </td> 
  </tr> 
</table> 

The following codes can be used to obtain the number of rows and columns of the table:

//表格行数 
var rows = document.getElementById("example_table").rows.length; 
 
//表格列数 
var cells = document.getElementById("example_table").rows.item(0).cells.length; 

You can use the above code to easily obtain the row number and column of the table through JavaScript. I hope this article will be helpful to your study.
