This is a simple Notepad++ plugin which gives you an interface for creating tables thats a little easier on the eyes.
To install, download the latest release or compile from source. Add the .dll to your Notepad++ plugins folder Program Files/Notepad++/plugins.
To use, click on the icon 
that is now on your toolbar.
The buttons are pretty self explanitory. The :---, ---:, and :---: buttons enter their contents into the cells you select. The Insert button puts your table as markdown where your cursor in Notepad++ is currently at. The Fill button takes the markdown table you have selected and inserts it into the interface table. Note: Fill will produce an error if your selection is not the same table format as the plugin generates.
Here is an example of the output:
| Hello | This is | A Header |
| :---: | :---: | :---: |
| and | here | are |
| some | | |
| | contents! | |
| Hello | This is | A Header |
|---|---|---|
| and | here | are |
| some | ||
| contents! |
