168680 WP plugin to edit post area

Hello, I need a wordpress plugin or widget made that will edit any template I use. The main thing I need is to edit the post area all other widgets out there only edit the sidebars not the post area. To use a 3 column template as an example I want to be able to add tables to the middle post area were all the blog posting is placed. I want to be able to move or add several post areas as well like move it around like a module or have more than one. There are two widgets or plugins that are perfect for what I need but they do not edit the post area only sidebars sidebar widgets and wp-table. You may be able to just customize both into one, I will upload sidebar widgets plugin zip file I can only upload one file you can google wp-table plugin so you can look over. Let me know what you think and if you have any questions.
