在此存儲過程中添加表格樣式？

有一天我在symantec link這個symantec link中發現了一個很好的存儲過程，它將TSQL表的結果轉換爲HTML表。沒有任何CSS參數，結果效果很好。我傾向於用SQL服務器結果發送大量電子郵件，所以這非常有幫助。在此存儲過程中添加表格樣式？

現在，我已經能夠使它工作了，我正試圖在桌子上添加一些樣式。問題是我不知道如何發送CSS class作爲參數。

例如，這裏就是我應該叫SP：

EXEC dbo.CustomTable2HTMLv3 'Buffy',@HTML1 OUTPUT,'class="horizontal"',0

的問題是，我不知道在哪裏的CSS classhorizontal從何而來。在鏈接中，我可以看到實際的CSS，但存儲過程如何讀取此內容？

的CSS是這樣的：

table.horizontal tr:first-child { 
background-color: Gray!important; 
font-weight: bold; 
color: #fff; 
}

這是存儲過程：

CREATE PROCEDURE [dbo].[CustomTable2HTMLv3] ( 
@TABLENAME NVARCHAR(500), 
@OUTPUT NVARCHAR(MAX) OUTPUT, 
@TBL_STYLE NVARCHAR(1024) = '', 
@ALIGNMENT INT =0) 
AS

當您從SSMS執行它時，它實際上是否添加了CSS樣式？ 如果表格將水平或垂直打印，則這由@Alignment參數定義。我認爲CSS本身不會被應用，如果你沒有指定源代碼或鏈接內聯樣式表。 –

不可以。它顯示純文本沒有顏色。格式是正確的，但沒有任何屬性可以給HTML任何樣式。 – rbhat

因此，在link您提供有以下提示：

「爲了幫助你設計你的表格樣式，我也在 的壓縮包裏下載了一個HTML文件，它有一個n嵌入樣式表中的元素 「。

所以，如果你打開他們提到那裏的html file，你會看到他們已經宣佈html本身內部的風格。 你只能通過SQL創建表，如果你喜歡，附上類名傳遞它作爲參數，但你將需要生成一個完整的HTML文件包含CSS（或引用它，沒關係）在爲了讓你的桌子風格。

正如我在評論中提到的，如果表格將水平或垂直打印，則僅由@alignment屬性定義，而不是由CSS class定義。 （您可以在存儲過程代碼中看到這一點）

我曾看過這個html文件，但它並沒有說我需要在文件中包含html以使其工作。 – rbhat

那麼，存儲過程只是生成表。沒有其他的。它會根據您提供的@TBL_STYLE參數來創建它，或者使用定義的css類或不使用css類。因此，如果您需要它包含某種樣式，則需要在編寫此過程的人員執行此操作時，將您的表放入具有某種嵌入或引用樣式的HTML文件中。 您也可以修改該程序，以便爲您創建整個html，而不僅僅是

。 :) –

考慮到在SP的第一個版本中，我可以包含實際的CSS作爲參數，我希望這個最後的版本會是類似的。不幸的是，事實並非如此。 – rbhat
