var but = document.createElement('span');
        but.innerHTML.id="but1"+inc;
        but.innerHTML = '<button value="delete row" id="'but'+inc"  
onclick="deleteRow(this.id)">delete row</button>';
// '"but"+inc' , "but+inc" are not working
//here inc is an integer value which increments by one

这是错误的

  but.innerHTML.id="but1"+inc;

应该是这样的

  but.id="but1"+inc;
  but.innerHTML = '<button value="delete row" id="but'+inc+'" onclick="deleteRow(this.id)">delete row</button>';
