推荐答案

如果您希望文本框具有列"，则可能需要调查使用文本框上的掩码来定义变量的多个列" -长度.您可以使用多个文本框，但是可能需要javascript才能在任何文本框上接收您的输入，并将值相应地写入texbox.

If you want a textbox to have "columns" you may want to investigate using masking on a textbox to define several "columns" of variable-length. You can use multiple textboxes, but it probably will require javascript to receive your input on any of the textboxes and write the value to the texboxes accordingly.

声音就像您正在寻找的一样某些蒙版文本框这样的东西，您将在其中显示要输入的数据格式. Google并使用它.
