Question

我尝试在包含我添加的第一个表的文件中写第二个表。没有重叠的行，文件被损坏但它插入表格，格式为excel formatAsTable样式都很好。我怎样才能消除这个问题。即使数据都很好，我也不能有一个损坏的文件。

public class formatAsTable2
{
  public static void main(String[] args)
    throws FileNotFoundException, IOException, InvalidFormatException
  {
      String[][] multi = new String[][]{
  { "Advisor", "notContacted", "appointmentsUTD", "totalWorkLoad", "notResponsiveCalls", "successfulCalls", "totalCalls", "totalIncomingEmails", "totalCommunication", "emailsSent","offerLetters","appFees","deposits" },
  { "Sharon Brown", "42", "44", "86", "62", "27", "89", "21", "220", "131" , "0", "6", "2", "0"},

};
      //(indexes start from 0) areaStart should be added to arenaRow
      int rowStart =55;   //From which row the table to start +1
      int columnStart =15; // From which column the table to start first column value 0

      int len = multi.length;
      int wid = multi[0].length;

Answer 1

每个表的DisplayName，Name和Id的{{1}}都必须是唯一的。因此，如果将新表附加到已有表的工作表，则必须确保它们是唯一的。

使用您的代码的示例：

CTTable
