fixes #993

Seems reasonable, just a weird Cypress error. I am assuming it is related since it's affecting the column-number.cy.js test, but have not looked into it.

I am wondering if instead of filling the default value then we should rather use the placeholder attribute and andjudt the check to allow empty fields for values that have a default? That way a default value would also adapt if changed on the table level.

I just noticed that this problem also affects other column types, not just the number column. Would look into making this approach more generic
