Dining Table Sizes Extra Large (avoid combining)

@jacksonvanmatre A few things that may possible help to know...

• There are threads at this link where you can voice your interest in adding items to the game with an increased possibility that EA will notice your idea and where others can add to the thread that they share interest in these changes to the game... which can serve to increase the priority that the feature gets attention: https://forums.thesims.com/en_US/categories/TS4-feedback 
• The new Island Life pack seems to have a round, casual table, but it does not look like an over-sized type (and I'm not sure if it is dining or not): https://youtu.be/KcbRY9Jv2ro There is also a longer, very formal table in the Get Famous pack, but I think this is also not what you mean.
• You can visit MTS (Mod The Sims). They have many forum discussions, tutorials, articles, creative ideas, creators posting and adding information and downloads, etc. there. You should be able to get questions answered and search for mods/cc, etc. there.
