学会Microsoft Excel基本

如果安排微软办公系统安装您，但从未接触了以前擅长，因为您二者之一不会使用它或不知道什么它可能为您做，则您在学会必须读这个岗位 如何使用擅长!

Microsoft Excel是可以为任何东西一直使用从一个简单的数据库由一种完全的窗口应用决定充分以窗口形式、宏指令和添加物的一种强有力的报表应用。您能使用擅长计算汽车贷款付款，注标数据，处理顾客纪录，保留地址本等等。

擅长当前使用多数大财政机关为每日财务数据分析。它有允许您使用财政作用，惯例的一个巨大的范围，并且添加物在一个简单，快的方式擅长存放和分析数据。

在本指南，我们审阅基本擅长：创造作业簿，使用活页练习题，进入的数据，使用惯例等等，以便您能变得舒适与软件和开始独自学会通过戏耍以它。

第一步到里擅长

首先，我们开始擅长并且看一看在节目的接口。开放擅长，并且一本新的作业簿将自动地被创造。作业簿是上层对象擅长。它包含活页练习题，举行所有实际数据与一起使用您。作业簿开始与三本活页练习题，但您能任何时候增加或删除活页练习题，只要有至少一本活页练习题在一本特定作业簿。

横跨上面，您有擅长工具栏，通常标准，并且允许您打开作业簿，创造新的，改变字体风格等等的格式化工具栏。这些是主要相同象词，但用我们以后将谈论的几个不同的按钮。

If you do not see the Standard and Formatting toolbars as shown above, you can have them brought back by going to View and then choosing Toolbars and check to make sure that the two toolbars have check marks next to them.

At the bottom of the screen, you’ll see three sheets, named Sheet1, Sheet2, and Sheet3. This is the default number that every Excel workbook starts off with.

On the right hand side of the screen is the Excel task pane, where you can perform many common tasks such as opening a workbook or creating a new one. You can also perform searches for help if needed here.

Getting Started with Excel

The best way to learn anything is to actually do something useful and Excel is the best example of this! Let’s say you are a teacher of high school or college students and you want to keep track of your student’s grades, calculate the average, and tell the students what grade they would have to get on their finals in order to get an A in the class.

Sounds like a simple problem and it is! Excel can do this for you very quickly, so let’s see how.

First off, let’s enter some data into the cells in Excel. In Excel, the columns are labeled starting from A and continuing to Z and beyond. A cell is simply a particular row number and column, i.e. A1 is the very first cell in an Excel worksheet.

Let’s type Students into well A1 and then type A through E as the student names continuing down column A as shown below:

Now let’s enter Test 1, Test 2, and Test 3 into cells B1, C1, and D1 respectively. Now we have a 5×4 grid, so let’s fill out some fake test grades also as shown below:

Now let’s learn some of the basics of formatting cells in Excel. Right now our table doesn’t look very nice since the text and numbers are aligned differently and the headers are not visually separate from the data.

First, let’s center all the data so that things look nicer. Click on cell A1 and drag your mouse down to cell D6 to highlight all entire grid:

Then on the Formatting toolbar, click the Center Justify button. The grid is now nicely centered with all the data directly underneath the headings.

Now let’s look more at how we can format Excel cells. Let’s change the color of the first row to something else so that we can clearly separate the header from the data. Click on cell A1 and drag the mouse while holding the button down to cell D1. Right click and select Format Cells.

In the Format Cells dialog, click on the Patterns tab and select a color from the palette. I chose yellow to give it a bright distinction.

Click OK and you’ll now see that the color has been changed for the selected cells.

Let’s also add some borders between the cells so that if we decide to print out the Excel sheet, there will be black lines between everything. If you don’t add borders, the lines you see in Excel by default do not print out on paper. Select the entire grid and click on Format Cells again. This time go to the Border tab. Click on the Outside and Inside buttons and you should see the small display box directly below the buttons change accordingly with the borders.

Click OK and you should now have black lines between all of the cells. So now we’ve formatted our grid to look much nicer! You can do this type of formatting for your data also in the way you feel appropriate.

How to use Formulas and Functions in Excel

Now let’s get to the fun part: using Excel functions and formulas to actually do something! So we want to first calculate the average grade for our 5 students after their 1st three exams. Excel has an average function that we can use to calculate this value automatically, but we’re going to do it slightly differently in order to demonstrate formulas and functions.

Add a header called Sum in column F and Avg in column G and format them the same way we did the other header cells.

Now first we’ll use Excel’s sum function to calculate the sum of the three grades for each student. Click in cell F2 and type in “=sum(” without the quotes. The = sign tells Excel that we plan on putting some type of formula into this cell. When you type in the first parenthesis, Excel will display a little label showing you what types of variables this function takes.

The word SUM is a built-in function in Excel which calculates the sum of a specified range of cells. At this point after the first parenthesis, you can select the range of cells you want to sum up! No need to type the cells one by one! Go ahead and select cells B2 to D2 and you will see that the formula is automatically updated and is in blue.

After you select the range, type in the closing parenthesis (Shift + 0) and press Enter. And now you have the sum of the numbers! Not too hard right!? However, you might say that it would be a royal pain to do this for a set of 100 or 500 students! Well, there’s an easy way to copy your formula automatically for the other students.

Click on cell F2 and then move your mouse slowly to the lower right edge of the cell. You’ll notice that the cursor changes from a fat white cross to a skinny black cross and the bottom right of the cell is a small black box.

Click on that small black box and hold your mouse down and drag it to the row of the last student. And with that, Excel uses the same formula, but updates the current row cells so that the sum is calculated for each row using that row’s data.

Next, click in cell G2 and type the = signs to denote we are starting a formula. Since we want to divide the sum by 3 to get the average, type the = sign and then choose the sum cell F2. Continue on with the formula by typing in “/3″, which means divide by 3.

Press Enter and you now have entered your own average forumla! You can use parenthesis and perform all the math functions in this same way. Now do the same thing as with the average and click the small black box at the lower right corner in cell G2 and drag it down to the bottom. Excel will calculate the average for the rest of the cells using your formula.

And lastly, let’s put in one more formula to calculate what each student would have to get on the final in order to get an A in the class! I’m assuming that the three tests were worth 70% of the grade, the final is worth 30%, and an A is 90 or above.

So in order to calculate the minium grade to get an A in the class, we have to take 90 and subtract 70% of the average test scores and divide the whole thing by 30%.

Min Grade To Get A: (90 - (.7 * AVG)) / .3

So let’s create a new header in column I and in cell I2, beging typing “=(90 - (.7 *” and then select cell G2 and then continue on with “))/.3″ and then press Enter. You should now see the grade required and also the formula in the formula bar above the column names.

Again, grab the bottom black box of the cell and drag it down to the bottom of the data set. And viola! You’ve now used Excel functions, created your own formulas in Excel and formatted cells to make them visually appealing.

Looks like Student C has to get a 118 in order to get an A in the class! Whoops!

Hope this helped! I’ll try and write more like this for more advanced features of Excel and other Office products. Please leave your comments on this Excel tutorital!
