问检查表格行中的单元格是否等于0，如果为0则隐藏行。

var tbl = document.getElementById('table');         //find the table
var rows = tbl.querySelectorAll('tbody tr');        //find all rows in the table body

for(i = 0; i < rows.length; i++) {                  //iterate through the rows

    var cells = rows[i].querySelectorAll('td');     //find all of the cells in the row

    var flag = true;                                //set flag prior to cell evaluation

    for(j = 2; j < cells.length; j++) {             //iterate through the cells (starting with the cell at position 2)
        if (cells[j].innerHTML != '0') {            //check if the cell contains '0' (set flag to false if cell is not '0')
            flag = false;                           
        }
    }

    if(flag) { 
        rows[i].classList.add('hide');              //hide the row if the falg remained true (i.e. none of the cells contained a value other than '0'
    }
}
