Frames Vs Tables
框架Vs表格

Some people like to use frames on their sites. I would recommend you avoid them if you can ... and you probably can.

有些人喜歡利用表格設計網站，但我建議你最好不要使用表格。我想你可以避免使用表格。

Frames can be useful on occasion but "the pain is greater than the gain". Too many people complain of problems with frames than you can afford to ignore. So if you insist on using them, you'll need to create an alternative no-frames set of pages for these users. Honestly ...

有時候，框架確實可以發揮作用，但它的缺點多于優點。你一定不能忽視框架的缺點，因為太多人已經在抱怨框架所帶來的問題。如果堅持使用框架，你需要為網站用戶創造另外一套無框架網頁。但誠實地說，

... it's just not worth the trouble!

這種做法太麻煩！

As If that wasn't enough reason, many search engine spiders also encounter difficulties with frames.

并且很多搜索引擎在搜索框架時，會越到一些問題。

This means you'll either have to spend additional time learning how to overcome these shortcomings or be doomed to low search rankings. Convinced?

這就意味著，你需要花費時間學習如何克服框架的缺點，否則網站注定會在搜索引擎中有一個低排名。

I hope so - for your sake!

我希望你的網站不會出現這種情況。

In most of the situations in which you might feel you need to use frames you can usually use tables equally effectively. If not on their own, then in conjunction with SSI - Server Side Includes - which also allow you to write separate pages for inclusion in another 'main' page.

大多數情況下，表格可以代替框架。利用表格的同時，你還可以使用SSI（Server Side Includes），它可以幫助你編輯主要頁面所包含的其它頁面。

The left column navigation bar, for example, is one area that it may seem appealing to place in it's own frame. The content remains the same on every page and should you need to change it, you can effect a global change just by altering a single file.

比如說，使用框架布局左列導航條，可能看起來很有吸引力。所有網頁布局一致，并且修改一個單獨文件之后，就可以改變所有網頁。

What many people don't realize that you can achieve almost the same result by using an SSI callout in a table cell within the page. This will reference another file on the server which will be written into this location when called. To browsers and search engine spiders alike the page appears as a normal web page and doesn't give rise to any of the problems associated with the use of frames.

很多人沒有意識到，在表格單元中利用SSI編號，也可以達到這個效果。這就會涉及到服務器中的另外一個文件，這個文件在需要時會設置到這個位置。瀏覽器與搜索引擎，更喜歡看似普通、不會出現框架問題的頁面。

　　

The Long Wait!

等一下！

Whilst we're on the subject of tables...

我們正在談論表格問題。

... don't make the same mistake I did when first using them!

第一次利用表格時，不要出現我曾出現過的問題。

Tables are great for page layout - you can put things just where you want them to appear on the page. So I made one big table for the whole page, split it up into various rows and columns, then put (nested) other tables inside these and in some places yet smaller ones inside them ...

表格是一種網頁布局的好方法，你可以根據需要，選擇網頁內容的位置。我在網頁中設計了一個大表格，劃分為很多行、很多欄，然后在內部表格中嵌套更小的表格。

Wrong! Wrong! Wrong!

錯誤！

Those of you that are quietly chuckling can stop now, thank you! Don't pretend you've never made the same mistake!

請你不要笑，我想你肯定犯過類似的錯誤。

Where was I ...?

我哪里出錯了呢？

Oh yes ... tables. Now the thing with tables is that the browser downloads all the contents of the table BEFORE it actually draws anything on the screen. This includes the contents of any nested tables. So what did that mean for my beautiful page?

是的，表格。這里的問題是，在表格內容下載完畢之前，瀏覽器不會在顯示屏中呈現任何內容。這就意味著，任何嵌套的內容都要下載完畢，那么這些布局精美的網頁會怎樣呢？

It took DAYS to download!

下載時間太長了！

Actually, it didn't really take that much longer, but it *seemed* like it did. The page remained completely blank until the browser had downloaded every single component and then suddenly flung them all onto the page at once! Leaving your visitors staring at a blank page for ages like this is not a good way to keep them on your site!

事實上，網頁下載不需要那么長時間。網頁首先會空白，瀏覽器下載完畢之后，網頁突然出現全部內容。如果網站訪問者長時間瀏覽空白頁面，他們很快會離開。

As ever, learn from your mistakes - or my mistakes! - and split your page up into several separate tables. Keep the whole lot as simple as possible and try to avoid nesting more than one layer of tables inside another. Browsers also take longer to draw tables if you don't specify the sizes. This is because the browser has to calculate how big the table needs to be to fit in all the contents.

繼續分析問題。我們應該避免在表格中嵌套其它表格，避免把表格繼續分割。如果表格尺寸沒有標明，瀏覽器下載表格的時間會比較長，因為，瀏覽器需要計算表格將會占用的空間。

You can also employ tables to add color to a page in preference to slow loading graphics. Or to effectively draw attention to text placed in a colored box on the page.

你可以利用表格填充網頁顏色，這樣比下載速度慢的圖片更好。或者把文本放置在網頁有顏色的表格中。

Tidy and Businesslike
整潔并且有條理

Forget about loud colors, blinking or scrolling text, fancy animated graphics ...

避免使用濃重的顏色、炫目或者滾動文本、奇怪的動畫圖像。

... anything that distracts the eye.

以及其它轉移用戶注意力的內容。

Your visitor needs to concentrate on your text if you want to get them to 'bite'. Compare your site to it's offline 'brick and mortar' equivalent.

網站必須保證用戶集中精力閱讀文字內容，這樣才可以吸引他們購買產品或服務。你可以參考實體商店，設計網站。

Would you paint that bright yellow and deck it out with flashing lights?

你會把網頁設計成嫩黃色或者很亮的顏色嗎？

... 'Nuff said!

最好不要！

Keep your pages clean and well organized. People must be able to find things easily.

網頁必須整潔、有條理，便于用戶尋找信息。

Imagine calling into a supermarket in a strange town to buy a box of tissues. You're in a hurry. To your dismay you find that none of the isles are labelled and you are forced to walk all over the store to find what you want.

假設，你在一個陌生城鎮的超市中匆忙地購買餐巾紙。使你掃興的是，商品沒有標簽，你需要在商店中到處尋找商品。

How annoyed and fed up would you feel?

你是不是感覺很苦惱呢？

Sure, you'd still buy ... but only because of the hassle involved in leaving the store and going to another. Online this is as easy as ...

當然，你肯定會購買，但你可能會去別的商店。網上購買也是同樣道理。

... click ... "I'm outta here!"

有些網站使用戶難以發現所需信息。

Actually, when you go to a supermarket you'll normally find that everything's neatly labelled and tidily displayed in rows with signs above them... build your online store along the same lines.

實際上，超市中的產品都很整齊，并且產品旁邊都會有標簽。構建網上商店時，遵循這些規則。

Apply what I call 'the three clicks rule'... make sure your visitor can find whatever they're looking for within three clicks. If not you run the risk of them becoming frustrated and leaving.

確保網站用戶在三次點擊之內，找到所需內容，否則他們會沮喪地離開網站。
