Original typography mode for chrome browser, table, tr, td.
A strange problem comes, the layout of the page initialization is normal, but when the input box is clicked,
The height of the input box is getting higher and higher.
After code inspection,
There are 2 lines in total, that is, 2 trs, but rowspan=2 is set in the td of the second line,
That is, extra space is taken up.
Chrome has a border effect every time the input is clicked
So it is estimated that the dom object of the page will be dynamically updated, so the problem arises
