Format spaces in bash output with echo [duplicate]

Question

Im trying to have some symple output, the issue is that I can't seem to set the spaces. I have to manually calculate what each variable will have. Is there a way to format table outputs better with echo?

This code

      echo """
      Datasets available to download are:
    
      Dataset   -   File Format
      ${dataset_one[6]}    -   ${dataset_one[5]}
      ${dataset_two[6]}  -   ${dataset_two[5]}
      ${dataset_three[6]}    -   ${dataset_three[5]}
    
      You currently have downloaded to hdfs the the following datasets:
      """

Returns:

  Dataset   -   File Format
  dataset1   -   csv
  ds2  -   csv
  datasnytaxi   -   parquet

I think column -t is what you are looking for:

-t Determine the number of columns the input contains and create a table. Columns are delimited with whitespace, by default, or with the characters supplied using the -s option. Useful for pretty-printing displays.
