I am using tables from [the Observable Inputs notebook(Observable Input: Table / Observable / Observable), but I notice I cannot embed the table as a iframe, and the preview window shows nothing. Is it because the Table function is still under development?
Be sure to fork the notebook, then name the cell, and finally republish (or link share) your copy. Then, you should be able to embed the cell. It looks like you did the first two but not the last.
I think I already published the copy, because I can embed other cell, not the cell containing the table.
@haoshuai If this is still an issue for you, then please share the link to your notebook here.
