Plugin for entries table field In Craft we have the table field type and each column can have a type. This field type is restricted to only text, number and checkboxes. Is there a plugin to add entries field type to the column types?

And if there isn't, can someone guide me to the proper files which I should look into to modify and add the field types myself by making a new plugin.
This question is from a long time ago, but nowadays there's a great 3rd-party plugin that lets you do this: https://github.com/engram-design/SuperTable
