Hello,
I am new to power apps portal application development. I have a scenario where I need to use a grid kind of input control on my web page from where I need to insert/update a bulk data at a time.
Please refer to the below screen shot, in an excel grid, I have two columns Name and birth date prepopulated with values, I only need City, Grade, Standard, and Percentage values to be inserted/ updated at a time.

what are the best possible ways to achieve this in power apps portal application?
quick help is really appreciated!!
Regards,
Pranesh
