Adding a column that spans entire table as child to each row

Thanks you very much @freva for the suggestion - that would work for me - thanks.

The Column E has no header, its used as a master/detail where we need to print a bunch of detail where we need more screen real estate to be able to display the information. That details are often multi lines of details. So a row could be (json output in details):

Column A | Column B | Column C | Column D
{
  "exchangeId": "29483200688F904-0000000000000009",
  "body": {
    "type": "java.lang.String",
    "value": "Hello2 Camel from java"
  }
}

My goal with the library is to keep it as simple as possible and supporting colspan is hard, supporting (in a general way) a single data element over multiple data rows is even harder.

But you can achieve the desired result if you generate a table, do some processing and generate another table. Say you have a List<Planet> as in the README with a JSON field, then you can do this:

Character[] style = {null, null, null, null, null, '|', null,
        null, null, null, null, null, '|', null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null};

// First create a table without the JSON row and only with the column separators, then split that into lines
String[] colRows = AsciiTable.builder().data(planets, columnData).border(style).asString().split(System.lineSeparator());
// Then create a list of rows, starting with the header and then intertwining the data rows with the header rows
List<String> data = IntStream.range(0, 2 * planets.size() + 1)
        // Substring to skip the padding char, since new padding that will be added by the new table
        .mapToObj(i -> i < 1 || i % 2 == 1 ? colRows[(i + 1) / 2].substring(1, colRows[0].length() - 1): planets.get(i / 2 - 1).json)
        .collect(Collectors.toList());
String table = AsciiTable.builder()
        .data(data, Arrays.asList(new Column().dataAlign(HorizontalAlign.LEFT).with(s -> s)))
        .asString();

Will produce
