Transcription

1 MS Excel is an example of a spreadsheet, a branch of software meant for performing different kinds of calculations, numeric data analysis and presentation, statistical operations and forecasts. The main part of a spreadsheet application is a grid consisting of equally (at least in a default view and configuration) distributed cells forming rows and columns. The rows are denoted by numbers (from 1 up to 65536, i.e ) and the columns by letters (from A to Z, then AA, AB up to IV, which makes a total number of columns equal to 256. i.e. 2 8 ). The cells are called by column and row identifiers, e.g. A3, G45, etc. current column current row active cell Active cell selection can be performed by means of mouse (simple clicking or keyboard arrows). The same refers to making a range selection (Ctrl and Shift keys are useful, especially in case of a discontinuous selections): discontinuous selection Exercise 1 Open MS Excel application and check different selection techniques on an empty worksheet. Try to make a selection as in the picture above. Check possibilities to select the whole tow/column by clicking on its header. Select multiple rows/columns, also discontinuously as in the picture below. Finally, select the whole worksheet by clicking on the upper-left corner (where row and column headers overlap, equivalent to Ctrl+A key combination). page 1 of 5

2 The most common way to enter data into a worksheet is just typing it. Accepting the cell value is done by: pressing Enter key (this moves the active cell one row down, useful when entering some column-sorted data), pressing Tab key (this moves the active cell one column right, useful when entering some rowsorted data), pressing any keyboard arrow, clicking somewhere outside the active cell. In order to delete the cell content, make it active and just press Delete key or Backspace key (this removes cell data and starts its edition). In case of cell edition, also select it as active. By double-clicking (equivalent to pressing F2 key), you start editing the data within the cell. If you want to overwrite current cell data, just start typing on it. However, very often it becomes more convenient to edit the cell data in a formula bar: active cell coordinates formula bar active cell Excel makes maximum effort to recognize data type (e.g. text, numeric, currency, date), which feature is usually ;) very useful and convenient. In case of each data type it applies appropriate alignment and some predefined display formats. Be careful about the data types recognized by the software while entering data, as sometimes its is very difficult to change them. Exercise 2 Enter the data ad in the picture above (in separate columns). Try entering dates using different formats (e.g , , 15 gru 04). Watch the software behaviour and compare the data displayed in cells with their actual data displayed in the formula bar. You can see what is the default data format of your entry in the drop-down list of the Number group of the Home tab. You can change the format form this list, or access to a wider choice from the Format Cells dialog box which can be activated by clicking on the little arrow at the bottom right side corner of the Number group. page 2 of 5

3 Exercise 3 Select data in column A (if you expect, that data in the whole column will be of the same type and display format, you can select the whole column). From the context menu choose Format cells option. Change cell format from general to number with 3 decimal places displayed: Compare the display format with values in the formula bar and during cell editing. Exercise 4 As in the previous exercise, change display format of column B to currency (English U.K.), as shown below: Exercise 5 Modify the date format in column D according to the example: Compare the display format with values in the formula bar and during cell editing. Exercise 6 By selecting columns and dragging them with the mouse ( catch selected column's border) change columns' B and D locations: Drag column B and drop it somewhere outside the data region. The place column D in an empty place. Finally, drag former column B to its new position. page 3 of 5

4 Exercise 7 Insert a new row between rows 3 and 4. Fill new cells with any data corresponding to columns' formats: Click on the fourth row's header and select Insert item from the context menu or on the Insert button of the Cells group (then select Insert Sheet Rows from the list). The new row will be inserted before the current row. Exercise 8 Adjust column widths according to the their content. You can manually drag column header borders enter a given size (between 1 and 255) in the Column width window from the context menu, or select the appropriate option from the Format button in the Cells group (for instance, Autofit Column Width). Select multiple columns if the operation should be the same for all of them. There is no need to repeat your action for each column separately. Exercise 9 Select the cell range occupied by you data. Catch the selection border and drag it so that it starts in cell B4: some values do not fit page 4 of 5

5 Apply Autofit Column Width (column widths have not changed while moving cells only cell values have been moved): Exercise 10 Format the data so that they look as a table (change fonts, borders, shading, override default alignments, etc). Add some dummy header. Try also formatting the table using Format as Table button from the Styles group : page 5 of 5
