我有一个表格，其中包含选项卡“创建”，“打开”，“编辑”和“文本框：过滤器”。 我正在创建一些带有标题名称和文本内容的注释。 使用Heading TestCheck，文本内容采用以下格式。
嗨test1 ..................
嗨test2 ...................
嗨test3 ..................

它在textArea中以此格式创建文本。但是当我点击Filter并选择Heading TestCheck时，它会刷新并减少到一行，它只显示中间行。

以下是文字签订合同的方法代码。

当我点击过滤器时，我必须避免文本内容的减少。在过滤时也应采用相同的格式。那么如何在线之间提供宽度来解决这个问题。
