Format an article into columns

Formatting long chunks of text into columns for display side by side.

[
    {
      "column 1": "The Kingdom of Scotland was a state in north-west Europe traditionally said to have been founded in 843, which joined with the Kingdom of England to form a unified Kingdom of Great Britain in 1707. Its territories expanded and shrank, but it came to occupy the northern third of the island of Great Britain, sharing a land border to the south with the Kingdom of England. ",
      "column 2": "Operation Barbarossa (German: Unternehmen Barbarossa) was the code name for Nazi Germany's invasion of the Soviet Union during World War II, which began on 22 June 1941. Over the course of the operation, about four million soldiers of the Axis powers invaded Soviet Russia along a 2,900 kilometer front, the largest invasion force in the history of warfare. In addition to troops, the Germans employed some 600,000 motor vehicles and between 600–700,000 horses."

Notice the columns above have equal width - this is the default style. You can give one or more columns a specific width using the --width option. In the example below we give "column 2" a specific width of 55 characters:

Include configuration options with the input

Table-layout expects an array of objects as the input. However, if the input data is a plain object with the fields options and data defined then these properties will be used as the table options and data respectively. Example:

{
    "options": {
        "noTrim": true,
        "columns": [
            { "name": "name", "width": 25 },
            { "name": "description", "width": 20 },
            { "name": "html_url", "width": 20, "break": true },
            { "name": "stargazers_count", "width": 5 }
        ]
    },
    "data": [
      ...
    ]
}

Please see this folder for examples of input containing both options and data.
