improve import function

I have an idea for this project.
Tried the import function. I had imported an excel document.
But the column title show on the content list. And need input the sub title again.
Suggest take the first column to be the title automatic. Or recognize excel freeze list to be the title.

## Why?
> Why we need this feature？
> What is the user story for this feature?
Import excel after can more less hand work. More automatic.
I had imported an excel. But the column title import on the content list. Then I need to input the column title and delete the content with the title column. If I don't delete the title on the content. Then the list number can't match the excel list number.

## What?
> Can you describe this feature in detail?
> Who can benefit from it?
Suggest take the first column to be the title automatic. Or recognize excel freeze list to be the title.

## How?
