JAVA Excel文件被损坏
我尝试在包含第一个我添加的文件中写第二个表。 没有重叠的行，文件被损坏，但它插入的表，格式化在excel formatAsTable风格一切正常。 我怎样才能消除这个问题？ 我不能有一个损坏的文件，即使数据都很好。
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"}, { "Elena Soteriou", "40", "44", "86", "62", "27", "89", "21", "230", "131" , "0", "7", "2", "0"}, { "Helen Christou","45", "44", "86", "62", "27", "89", "21", "210", "131" , "0", "8", "2", "0"}, { "Maria Georgiou", "48", "44", "86", "62", "27", "89", "21", "240", "131" , "0", "45", "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; int areaRow =len+rowStart-1; // how many rows the table has int areaColumn=wid+columnStart-1; //how many columns the table has /* Start with Creating a workbook and worksheet object */ InputStream inp = new FileInputStream("Excel_Format_As_Table.xlsx"); XSSFWorkbook wb = (XSSFWorkbook) WorkbookFactory.create(inp); XSSFSheet sheet = (XSSFSheet) wb.getSheetAt(0); /* Create an object of type XSSFTable */ XSSFTable my_table = sheet.createTable(); /* get CTTable object*/ CTTable cttable = my_table.getCTTable(); /* Let us define the required Style for the table */ CTTableStyleInfo table_style = cttable.addNewTableStyleInfo(); table_style.setName("TableStyleMedium20"); /* Set Table Style Options */ table_style.setShowColumnStripes(false); //showColumnStripes=0 table_style.setShowRowStripes(true); //showRowStripes=1 /* 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 */ cttable.setRef(my_data_range.formatAsString()); cttable.setDisplayName("MYTABLE"); /* this is the display name of the table */ cttable.setName("Test1"); /* This maps to "displayName" attribute in <table>, OOXML */ cttable.setId(1L); //id attribute against table as long value //cttable.addNewAutoFilter(); CTTableColumns columns =cttable.addNewTableColumns(); columns.setCount(areaColumn); //define number of columns /* Define Header Information for the Table */ for (int i = columnStart; i <= areaColumn; i++) { CTTableColumn column = columns.addNewTableColumn(); column.setName("Column" + i); column.setId(i+1); } int x =-1; int y =-1; /* Add remaining Table Data */ for (int i=rowStart;i<=areaRow;i++) //we have to populate 4 rows { ++x; y=-1; /* Create a Row */ XSSFRow row = sheet.createRow(i); for (int j = columnStart; j <= areaColumn; j++) //Three columns in each row { ++y; XSSFCell localXSSFCell = row.createCell(j); if (i == rowStart) { localXSSFCell.setCellValue("Heading" + j); } else { localXSSFCell.setCellValue(multi[x][y]); } } } System.out.println("X"+x); System.out.println("y"+y); inp.close(); /* Write output as File */ FileOutputStream fileOut = new FileOutputStream("Excel_Format_As_Table.xlsx"); wb.write(fileOut); fileOut.close(); } } import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import org.apache.poi.openxml4j.exceptions.InvalidFormatException; import org.apache.poi.ss.usermodel.WorkbookFactory; import org.apache.poi.ss.util.AreaReference; import org.apache.poi.ss.util.CellReference; import org.apache.poi.xssf.usermodel.XSSFCell; import org.apache.poi.xssf.usermodel.XSSFRow; import org.apache.poi.xssf.usermodel.XSSFSheet; import org.apache.poi.xssf.usermodel.XSSFTable; import org.apache.poi.xssf.usermodel.XSSFWorkbook; import org.openxmlformats.schemas.spreadsheetml.x2006.main.CTTable; import org.openxmlformats.schemas.spreadsheetml.x2006.main.CTTableColumn; import org.openxmlformats.schemas.spreadsheetml.x2006.main.CTTableColumns; import org.openxmlformats.schemas.spreadsheetml.x2006.main.CTTableStyleInfo; 显示Name ， CTTable的Name和Id需要对每个表都是唯一的。 所以你必须确保它们是唯一的，如果你添加新的表格已经有表格。
使用你的代码的例子：
... /* 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 ...
