[英]JAVA Excel files get corrupted
我尝试在包含我添加的第一个表的文件中写入第二个表。 没有重叠的行,文件被破坏,但是它插入表格,以excel formatAsTable样式格式化,一切都很好。 我该如何解决这个问题。 即使数据都很好,我也无法拥有损坏的文件。
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"},

每个表的DisplayName
, CTTable
的Name
和Id
必须是唯一的。 因此,如果将新表追加到已有表的工作表中,则必须确保它们是唯一的。
使用代码的示例:
...
/* Define the data range including headers */
AreaReference my_data_range = new AreaReference(new CellReference(rowStart, columnStart), new CellReference(areaRow, areaColumn));
/* Set Range to the Table */
String wantedDisplayName = "MYTABLE";
String wantedName = "Test1";
long id = 0L;
java.util.List<XSSFTable> all_tables = sheet.getTables();
for (XSSFTable a_table : all_tables) {
if (wantedDisplayName.equals(a_table.getDisplayName())) wantedDisplayName += "_1";
if (wantedName.equals(a_table.getName())) wantedName += "_1";
if (a_table.getCTTable().getId() > id) id = a_table.getCTTable().getId();
System.out.println(wantedDisplayName);
System.out.println(wantedName);
System.out.println(id);
}
id++;
cttable.setRef(my_data_range.formatAsString());
cttable.setDisplayName(wantedDisplayName); /* this is the display name of the table */
cttable.setName(wantedName); /* This maps to "displayName" attribute in <table>, OOXML */
cttable.setId(id); //id attribute against table as long value
