tr顯示後不顯示全部長度：無

我在td中有一個下拉菜單。有3個我已經設置的tr顯示：無html。基於下拉列表選擇，我使用JQuery顯示了這3個表中的一行。tr顯示後不顯示全部長度：無

它運作良好，但有一個問題。當我設置tr顯示時，它不會全長。如果我刪除顯示：在HTML中沒有任何一個顯示全部長度。請指導我，這裏是我的代碼：

function ddlChange() {   
    var index = $('select[id$=ddlSchoolFundingType]').get(0).selectedIndex;   
    if (index == 1) {    
     $('#ERIRow').css("display", "inline"); 
     $('#StudentRateRow').css("display", "None"); 
    } 
    else if (index == 2) { 

     $('#ERIRow').css("display", "none"); 
     $('#StudentRateRow').css("display", "inline"); 
    } 
    else {   
     $('#ERIRow').css("display", "none"); 
     $('#StudentRateRow').css("display", "none"); 
    } 
}
