Updateing design tables in drawing

I have a drawing with design tables in it and there are just a few of the columns and rows that I would like in the table so I've hidden the rows/columns that I don't want visible. my problem is when I save the drawing it updates the table and moves to the last column and updates to that view in the drawing. how do I keep the table up to date in the dwg but not have to go back in to the part and re set the table each time I save the document. It is costing me a lot of time. By the way, at one time well working on the parts I lost the design table and I had to open the table from the drawing in a different window save the file then reattach the table in the part. this put the design table icon back in the feature manger. The weird thing was that with the design table gone from the feature manager the configs were still there in the config manager. can some one explain?
