Insert row with a slice helper

[cemremengu]

There should be a helper function for inserting a new row but instead of empty, I should be able to provide a slice containing row data.

The function will create the row with cells populated with data (maybe assuming all are strings). There may also be an offset column parameter.

Thanks for your issue. Same as the issue #96, I have added this feature request to the Roadmap. I closed this issue and continue the discussion on issue #96.
