Would it make sense to have a setting that can limit the amount of text displayed in any given cell in the table preview, or (less useful?) suppress (with notification) the display of overlong columns unless enabled by the user? An issue then arises if a user does want to see all the text in a cell: 1) for a particular cell; 2) for every cell in the table; 3) for all cells in a particular column or columns (I haven't checked but what if a column contains e.g. raw image data? Does this display as raw data? Or can this be rendered in a context aware way as an image preview? I guess a custom template would be one way to do that?)",107914493,issue,,,"{""url"": ""https://api.github.com/repos/simonw/datasette/issues/330/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,completed
