hello,How does the content of hello and datatable occupy the whole component on average

Hello @JACK_CHYMBCC,
I’m afraid the description of the issue is not clear for us. Could you please clarify the use-case?

I’m sorry that I didn’t express myself clearly, but I have solved the problem of automatically filling the height of rows in the DataTable in the panel, but the contents in the rows can’t be vertically centered
