Steps to Reproduce

import {TableExportPlugin} from '@visactor/vtable-plugins';

    const tableExportPlugin = new TableExportPlugin({
        exportExcelOptions: {
            exportAllData: true,
            downloadFile: false,
            // fileName: `${name}-${dt}`
            formatExcelJSCell: (cellInfo, cellInExceljs) => {
                if (cellInfo.col === 1) {
                }
                // delete cellInExceljs.style.fill;
                return cellInExceljs;
            }
        },
    });

Current Behavior

原表格样式

导出Excel的样子

Debug看了下黑色背景的单元格没有差异

Expected Behavior

正确显示背景色
另外，数字单元格现在都是以文本形式展示，建议设置为数值之后使用exceljscell的numFmt格式化

Environment

- OS:
- Browser:

Any additional comments?

No response

Start from the TableExportPlugin configuration and its formatExcelJSCell export path, using the provided snippet to reproduce the Excel output. Compare exported cell fill styles with the source table and check how numeric cells are typed and formatted. Done means background colors render correctly and numeric cells are exported as numbers with the expected formatting.
