A blank problem occurs between two tables due to the addition of form in js.

Add CSS in & lt; FORM & gt; & lt; table & gt ;....... & lt;/table & gt; & lt; formstyle & quot; padding: 0; margin: 0; & quot; & gt; & lt; inputname & quot; & gt; & lt;/form & gt; & lt; table & gt ;.....

In

.......

Note: In Firefox

Problems may occur.

 

I have seen another saying on the Internet that creating a form in a table does not comply with the DOM standard, which will lead to post failure and js data transmission failure.
