我从postgresql获取输出。我想让它变得如此清晰。
例如:
content | tablename | columnname | rowctid
------------+-----------+------------+---------
blabla | s3 | usename | (0,11)
public1 | s2 | relname | (7,29)
public 2 | w | body | (0,2)
我如何使用制表机等?我将从这开始,例如:
System.out.println(" content | tablename | columnname | rowctid");
System.out.println("------------+-----------+------------+---------");
for (int i = 0, i<x, i++) {
System.out.println(con_var + " | " +tab_var + " | " +col_var + " | " +row_id);
}
但我认为制表师并不工作。另外,如果一个单词比另一个单词长,那么&#39; |&#39;会站在不同的位置。

试试这样:
System.out.println(String.format("%30s", "content |")
+ String.format("%30s", "tablename |")
+ String.format("%30s", "columnname |")
+ String.format("%30s", "rowctid |"));
System.out.println(String.format("%30s", "+").replaceAll(" ", "-")
+ String.format("%30s", "+").replaceAll(" ", "-")
+ String.format("%30s", "+").replaceAll(" ", "-")
+ String.format("%30s", "+").replaceAll(" ", "-"));
for (int i = 0, i<x, i++) {
System.out.println(String.format("%30s", con_var + " | ")
+ String.format("%30s", tab_var + " | ")
+ String.format("%30s", col_var + " | ")
+ String.format("%30s", row_id + " | "));
}
在此示例中,30是列大小。根据需要进行更改。
