How to vertically centre a data picker within a table

Hi everyone, I’ve been trying for the past hour to vertically centre a date picker that I’ve got within a table cell so it matches up with the rest of the page.

Do you mean with table cell that all the elements are inside the same <td> element? In that case, you could try adding vertical-align: middle; as style. 

Vertical alignment in tables can be tough, that is why Mendix switched to layoutgrid (probably not the only reason), which use flexbox. Rows and colums in layoutgrid can be centered vertically ( and 

If you want to keep using tables, you could also wrap the elements inside your table cell in a container and give the container the class ‘row-left’ (or row-center or row-right), which makes the container into a flexbox aligning the inside elements vertically in a row. They are also in the helper files mentioned by Mike.
