java - 自动换行 :break-word is not working with iText 2. 1.7

Question

我正在使用 Java 和 Itext2.1.7 来生成 pdf 并且我编写了以下 HTML。但当它们太长时，它并不是断词。

String td ="<td colspan=\"2\" align=\"left\" style=\"table-layout: fixed;word-wrap:break-word;white-space: normal;\"><b>"
                    + verylongwordverylongwordverylongword + ":</b></td>"

有人可以帮我实现这个目标吗？

Itext 2.7.1 不支持 word-wrap : break-word 属性。以下是该链接。

因此，我根据表的列数并假设最大字母在 60-65 左右来手动拆分单词。以下是相关代码。

public String getBrokenWordsForPdfGeneration(String longString, int cutIndex){
       StringBuffer mainStringBuffer = new StringBuffer(longString);
       String returnString = "";
       while(mainStringBuffer != null && mainString.length()>0 &&                              
mainString.subString(0,mainString.length()>cutIndex?cutIndex:mainString.length()) != null){ 
          if(mainStrig.subString(0,mainString.length()>cutIndex:mainString.length()).trim().contains(" ")){
               returnString += mainStrig.subString(0,mainString.length()>cutIndex:mainString.length()).trim();
               mainStringBuffer.delete(0,mainString.length()>cutIndex:mainString.length());
          }else{
              returnString += mainStrig.subString(0,mainString.length()>cutIndex:mainString.length()).trim()+ " ";
              mainStringBuffer.delete(0,mainString.length()>cutIndex:mainString.length());
          }
    }
    return returnString;
}
