推荐答案
如果您不希望（或不允许出于某种原因）使用库，你可以使用标准的PHP的 的printf /的 的sprintf 功能。
If you don't want (or not allowed for some reason) to use libraries, you can use standard php printf / sprintf functions.
与他们的问题，如果你有可变的和非宽度有限值，那么你将不得不决定是否长期价值将被截断或破坏表的布局。
The problem with them that if you have values with variable and non-limited width, then you will have to decide if long values will be truncated or break table's layout.
第一种情况：
// fixed width
$mask = "|%5.5s |%-30.30s | x |\n";
printf($mask, 'Num', 'Title');
printf($mask, '1', 'A value that fits the cell');
printf($mask, '2', 'A too long value the end of which will be cut off');
输出为
| Num |Title | x |
| 1 |A value that fits the cell | x |
| 2 |A too long value the end of wh | x |
第二种情况：
Second case:
// only min-width of cells is set
$mask = "|%5s |%-30s | x |\n";
printf($mask, 'Num', 'Title');
printf($mask, '1', 'A value that fits the cell');
printf($mask, '2', 'A too long value that will brake the table');
在这里，我们得到
And here we get
| Num |Title | x |
| 1 |A value that fits the cell | x |
| 2 |A too long value that will brake the table | x |
如果没有的满足您的需求，你真的需要一台具有流动列宽，比你要计算每列值的最大宽度。但是，这是多么 PEAR :: Console_Table 完全适用。
If neither of that satisfies your needs and you really need a table with flowing width columns, than you have to calculate maximum width of values in each column. But that is how PEAR::Console_Table exactly works.
