Can I plug an IEC rated for 10A into the wall?
If I understand your question, the answer is no.  Or, yes, you &quot;can&quot;. But no, you should not use a hollow table as the electrical enclosure for a home-made power strip unless the table was actually designed to be an electrical enclosure.
Instead you should buy ready-made boxes that do what you want.  If you want to have power outlets embedded in a table, there are a lot of ready-made modules to do that.  Search for &quot;recessed table outlets&quot; &quot;recessed conference outlets&quot; and so on.   Some of them pop up in cute ways.  Some of them have built in USB charging.  Most of them have built-in power cords under the table presumably because that is cheaper than using an IEC connector and avoids the risk of users kicking the cable out.  But some do have female IEC connectors instead so you can use separate power cords.  Some of them can be daisy chained so you can install recessed outlets in different parts of a large table, while having only one power cord connecting the table to the wall or floor.  That sounds like what you want to do, but a lot safer.
If you use daisy-chained ones perhaps you could route the double-insulated cables between them through your hollow table.   Again, a more ready-made way to do this would be to install a $2 plastic channel under the table, or just use staples.
