Tables A table in Excel is a rectangular array of information/attributes where the first row is normally used for headers for each column of information. Each row in a table usually represents a single object that has different types of information related to it. Excel has the ability to format rectangular array data effortlessly.
Creating Tables There are three basic ways to create a table in Excel: The first way is to highlight the array of cells you would like to make a table out of and then press CTRL+T Another way is to highlight the cells of interest and then go to the Insert tab and select the table button. On the Home tab, you can select the Format as Table Button.
Header Row for Tables When you create a table out of an array of data, Excel puts drop down arrows in the header row that allow you to: Sort the data (either ascending or descending) Filter the data, i.e., choose particular rows of the data based on criteria Select certain data
Design Tab Whenever you have a table and you have selected an item in the table, you should notice that the Design tab appears. This tab gives you the ability to: Give the table a name, Resize the table,
Design Tab Cont. Summarize with a pivot table, Remove duplicate values, Convert to a normal range, and Insert Slicers.
Table Styles and Options When you create a table out of an array of data, Excel has many preprogrammed formats located under Table Styles and Table Style Options. Under Table Style Options, you have the ability to add and delete: Header Row, Total Row, Banded Rows, Banded Columns, and Filter Button.
Table Styles and Options Cont. You can also bold the First Column and Last Column.
Slicers A slicer is a quick way to have a tool that allows you to quickly examine particular aspects of your data. It is basically another filtering device. You can right click on the slicer to bring options that you can do or use the options tab.
Referencing Columns in Formulas Once a table has been defined, you can reference that table anywhere in your spreadsheet to use in a function. For example, if you wanted to average a particular column of information where the column name is 2011 Value and the table name is Commodity, your formula would be =Average(Commodity[2011 Value]).
Adding a Calculated Column Excel has the ability once a table is established to create a new calculated column off of other columns in the table. You only need to enter the formula for the first cell and Excel will create a new column and copy the formula down.
Referring to Particular information in a Table #All refers you to all the cells in the table including the total row if it exists. #Data refers to all the cells in the table except for the header and row columns. #Headers refers only to the header row. #Totals refers to the total row. #This Row refers to cells in the current row.
In-Class Activity Given the data in Sheet1 in the TablesExamples.xlsx workbook, investigate/do the following: Make a Table out of cells A3 through W36 Name the Table FruitAndTreeNuts Try reversing the data by Years where 2012 is the first row, 2011 is the second row,
In-Class Activity Cont. Try showing only data for the Years 2000 through 2009 Add a Total Row that has Average for one column, sum for a second column, count for a third column Create a Slicer for Lemons and change its title to Lemon Receipts
In-Class Activity Cont. In cell B40, use the sum function to add up all the receipts for Grapefruit. What does the formula look like? In column X, sum up each row. What does the formula look like for each row?
In-Class Activity Cont. Add two rows between 2012 and the Total Row. In each cell use the RandBetween function pulling the minimum and maximum as the arguments to the function to fill out the table for the two new added rows. What happened?
