In this previous post we saw some code to create a table style and apply it to a new table inside an AutoCAD drawing. While responding to a comment on the post, I realised that the table didn't display properly using my example: the first column heading was being taken as the table title and the rest of the column headings were lost - the headings in the table were actually taken from the first row of data. I suppose that serves me right for having chosen such eye-catching (and distracting) colours. 🙂
The following C# code addresses this by adding some information to our array of table contents, and using that for the table title. It also does a little more to customize the display of our table by applying chunky lineweights (and yet more garish colours) to the table's grid-lines.

One other minor enhancement: I made use of the TableStyle.PostTableStyleToDatabase() method to add the style to the appropriate location in the Database (we previously edited the TableStyleDictionary directly to achieve this).
Here's what happens when we run the CTWS command (making sure that we have adjusted the display settings to use lineweights):
And here's the updated style in AutoCAD's TableStyle dialog:
That's better. At least in that it does what was expected of it, even if it's not winning any design awards. 🙂
Update
Roland Feletic pointed out that this code - while it still builds for AutoCAD 2011 - causes some "obsolete property/method" compiler warnings. I've provided an updated version of the code below, with the previous lines commented out for comparison:
