title: Golang google sheets API V4 - Write/Update example?
body: <p>Trying to write a simple three column table (<code>[][]string</code>) with Go, but can't. 
  The <a href="https://developers.google.com/sheets/quickstart/go" rel="noreferrer">quick start</a> guide is very nice, I now can read sheets, but there no any example of how to write data to a sheet, maybe it is trivial, but not for me it seems. 
  The <a href="https://github.com/google/google-api-go-client/tree/master/sheets/v4" rel="noreferrer">Golang library</a> for my brains is just too complicated to figure out.
  And there not a single example I could google... </p>
  
  <p>This <a href="https://stackoverflow.com/questions/37462887/google-sheets-api-v4-c-sharp-update-a-cell">C# example</a> very looks close, but I am not sure I clearly understand C#</p>
