  const templatePlaceholder = `模板信息格式：key标识数据库column列名称（在join模式下需要写为 table.column），value标识导出excel列名称，如key为数据库关键字或函数，请按照关键字的处理模式处理，当前以mysql为例，如下：
{
  "table_column1":"第一列",
  "table_column3":"第三列",
  "table_column4":"第四列",
  "\`rows\`":"我属于数据库关键字或函数",
}
如果使用是sql模式，您自行构建的sql的key就是需要写在json的key，例如您写了xxx as k1，那么模板信息中就写{"k1":"对应列名称"}
如果增加了JOINS导出key应该列为 {table_name1.table_column1:"第一列",table_name2.table_column2:"第二列"}
如果有重复的列名导出格式应为 {table_name1.table_column1 as key:"第一列",table_name2.table_column2 as key2:"第二列"}
JOINS模式下不支持导入
