I created screens and window which is shown below. The first problem I face is that when I clicked Save button, only the first row of the table in RFQ is saved. Both "RFQ1810002" and "RFQ1810003" did not save.

Besides, the second question is that when I reload the page. The "RFQ" Table is empty and data inside the table show when I click on the first row/ press "Enter" (only the first row contain data"RFQ1810001")

Please give me some advice or suggestion on these problem. Thanks!
