将excel模板转化为html到前端页面填写

要将Excel模板转换为HTML，可以使用Java中的Apache POI库。以下是一个简单的示例代码，它将Excel模板转换为HTML：

import java.io.*;

import org.apache.poi.ss.usermodel.*;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import org.apache.poi.ss.util.CellAddress;
import org.apache.poi.ss.util.CellRangeAddress;

public class ExcelToHtmlConverter {
    public static void main(String[] args) {
        try {
            // Load Excel workbook
            FileInputStream inputStream = new FileInputStream(new File("path/to/excel/file"));
            Workbook workbook = new XSSFWorkbook(inputStream);

            // Get the first sheet
            Sheet sheet = workbook.getSheetAt(0);

            // Create a new HTML table
            Writer output = new PrintWriter("path/to/html/file", "utf-8");
            output.write("<table>");

            // Loop through rows and columns to create HTML rows and cells
            for (int i = sheet.getFirstRowNum(); i <= sheet.getLastRowNum(); i++) {
                Row row = sheet.getRow(i);
                if (row != null) {
                    output.write("<tr>");
                    for (int j = row.getFirstCellNum(); j <= row.getLastCellNum(); j++) {
                        Cell cell = row.getCell(j);
                        if (cell != null) {
                            // Get cell value
                            String value = "";
                            switch (cell.getCellType()) {
                                case STRING:
                                    value = cell.getStringCellValue();
                                    break;
                                case NUMERIC:
                                    value = Double.toString(cell.getNumericCellValue());
                                    break;
                                case BOOLEAN:
                                    value = Boolean.toString(cell.getBooleanCellValue());
                                    break;
                            }

                            // Get cell address and span
                            CellAddress address = cell.getAddress();
                            int rowspan = 1, colspan = 1;
                            for (CellRangeAddress range : sheet.getMergedRegions()) {
                                if (range.isInRange(address)) {
                                    rowspan = range.getLastRow() - range.getFirstRow() + 1;
                                    colspan = range.getLastColumn() - range.getFirstColumn() + 1;
                                    break;
                                }
                            }

                            // Create HTML cell
                            output.write("<td rowspan=\"" + rowspan + "\" colspan=\"" + colspan + "\">" + value + "</td>");
                        }
                    }
                    output.write("</tr>");
                }
            }

            // Close the HTML table
            output.write("</table>");
            output.close();

            // Close the workbook
            workbook.close();

            // Display success message
            System.out.println("Excel converted to HTML successfully!");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

以上代码将Excel模板转换为HTML文件并保存在指定的路径中。在前端页面中，可以使用任何HTML表格渲染库来呈现此表格。
