我认为这很简单：
public static void main(String... args) throws IOException { ArrayList<ArrayList<String>> rows = getRandomData(); if (rows.size() == 0) throw new RuntimeException("No rows"); // normalize data int longest = 0; for (List<String> row : rows) if (row.size() > longest) longest = row.size(); for (List<String> row : rows) while (row.size() < longest) row.add(""); if (longest == 0) throw new RuntimeException("No colums"); // fix special characters for (int i = 0; i < rows.size(); i++) for (int j = 0; j < rows.get(i).size(); j++) rows.get(i).set(j, fixSpecial(rows.get(i).get(j))); // get the maximum size of one column int[] maxColumn = new int[rows.get(0).size()]; for (int i = 0; i < rows.size(); i++) for (int j = 0; j < rows.get(i).size(); j++) if (maxColumn[j] < rows.get(i).get(j).length()) maxColumn[j] = rows.get(i).get(j).length(); // create the format string String outFormat = ""; for (int max : maxColumn) outFormat += "%-" + (max + 1) + "s, "; outFormat = outFormat.substring(0, outFormat.length() - 2) + "n"; // print the data for (List<String> row : rows) System.out.printf(outFormat, row.toArray());}private static String fixSpecial(String s) { s = s.replaceAll("(")", "$1$1"); if (s.contains("n") || s.contains(",") || s.contains(""") || s.trim().length() < s.length()) { s = """ + s + """; } return s;}private static ArrayList<ArrayList<String>> getRandomData() { ArrayList<ArrayList<String>> data = new ArrayList<ArrayList<String>>(); String[] rand = { "Do", "Re", "Song", "David", "Test", "4", "Hohjoh", "a "h" o", "tjo,ad" }; Random r = new Random(5); for (int i = 0; i < 10; i++) { ArrayList<String> row = new ArrayList<String>(); for (int j = 0; j < r.nextInt(10); j++) row.add(rand[r.nextInt(rand.length)]); data.add(row); } return data;}输出（因为它是随机的，所以很难看）（转义）：
