This plugin generates table tags with simple operations. 
You can merge cells by dragging and clicking, and enter the characters directly in the table. 
VERY EASY!
<h4>How to use</h4>
<ol>
<li>First, please choose the size of the table (rows and columns). You can type on the keyboard a number, click on the spinner, or turn the mouse wheel.</li>
<li>If you want to use <th> element instead of <td> element (or vice versa), please drag to select the cells you want to convert, and click on the “td ↔ th” button.</li>
<li>If you want to merge cells, please drag to select them and click the “merge” button. Merged cells can be undone in the “split” button.</li>
<li>If you enter characters in the table, please click the “chars” button, and be set to an input mode. When you are done, please click on the “output” button.</li>
<li>To apply the CSS, it is possible to set the class attributes for the cells.</li>
<li>All operations can be undone by clicking the “undo” button.</li>
