One of the key benefits of tables is how other features in Excel 12 behave more predictably and more like you would expect when a table is present. This is made possible by the fact that Excel knows exactly where the table starts and ends, where the header row is, which cells make up the data and which columns they belong to, where the total row is, etc. So how exactly does this benefit the user? Here are some of the different ways in Excelâs awareness of the structure of your data changes the user experience.
When a user does something to a column of data in a table, it “sticks”. What exactly does that mean? If, for example, a user applies a conditional format to an entire column of a table, Excel assumes that the conditional format is always meant to cover the entire table column. So as new rows are added to the table, either in the middle or at the end, and as rows are deleted, Excel will automatically extend or contract the conditional formatting rule appropriately. The rule âsticksâ to the column. We already saw this with the example in my previous post, but it doesnât just stop with conditional formatting. This concept works with just about anything you can apply to a column, such as formatting (anything in the Format Cells dialog), cell protection, data validation, etc. In addition, this behaviour also applies to anything that holds on to a reference, such as formulas, charts and PivotTables.
How do you make something âstickyâ? Thereâs no explicit gesture for this. Excel just assumes that anytime something is done to an entire column, the setting is meant to always follow the column. So, if a user selects a table column and applies a data validation rule, that rule will grow and shrink with the table. Create a PivotTable that uses a table as its data source, and that Pivot Table will automatically pick up new rows from the table. Ditto for charts. To be precise, when I say âentire columnâ in this context, I really mean all the data rows. It is not necessary to also include the header cell – this way you donât have to include the header in order to, for example, make the âcurrencyâ number format stick to a column for example.
This stickiness also applies to new columns. For example, if a table is used as the data source for a chart, then any new columns I add to the table will get picked up by the chart. In addition, properties set on the entire table, headers, and the total row (more on what a total row is in a later post) are also “sticky”.
Now that Excel recognizes things like rows and columns in my tables, it is only natural that it provide simple ways to select those elements of a table. A single mouse click can select one or more rows, one or more columns, or the entire table. To select a column in a table, simply hover the mouse over the top of the header until the mouse cursor turns into a down-arrow and click.
To select a row, hover the mouse over to the left edge of a row until the mouse cursor turns into a right-arrow and click. And to select the entire table, hover the mouse over the top-left corner of the table until you see an arrow that points down and right and click.
Note that column and table selection have two behaviours. The first click always selects just the data portion of the column/table. This makes it easy to select a column of numbers and apply formatting or other properties to the data in the column. The second click expands the selection to cover everything in the column/table, header and all. This is useful for copy/paste operations or rearranging columns in a table.
If you are a keyboard junkie (like many of the people reading this seem to be), note that there is keyboard support for these selection behaviours. The existing shortcut keys for row and column selection, SHIFT+SPACE and CTRL+SPACE respectively, have been modified to work with tables. For example, pressing CTRL+SPACE once selects all the data rows in a table column. The second press expands the selection to encompass the entire table column, and the third press expands it again to encompass the entire worksheet column.
What Column am I in again?
This is one of my favorites. When working with large data sets, itâs easy to scroll the headers off the screen and forget which column you are looking at, especially if many of the columns have similar data in them. Once you have declared something a table in Excel 12, this problem will go away – when navigating a large table and the tableâs headers have been scrolled off the screen, Excel will insert the table headers into the sheet header row where the A, B, C headings appear (see the screen shot below). For example, when I scroll this table upwards â¦
â¦ the header text shows up in place of the sheet headers.
This makes it much easier to keep track of things without having to split screen/freeze panes. Note, the table headers will only be visible as long as the active cell is somewhere inside the table. If you select outside the table, the standard A, B, C headers return.
More Conditional Formatting Goodness
Back at the start of my conditional formatting posts, I said that one of the things we set out to do was to provide a better experience in Tables – lowering the bar for conditional formatting rules that previously required formulas or fiddling. Here are two features we added to conditional formatting when a user is working with a table.
First, we added a âformat entire rowâ option that appears when defining a conditional format rule on a table.
When this option is turned on, the entire table row will be highlighted when a condition is met within a specific column. Achieving this in the past required more advanced knowledge of conditional formatting. Now you can treat it like any simple rule â just select the olumn you are interested in evaluating, and select this option if you want the result to show across the entire row.
Second, we added a âcompare columnsâ rule to the list of rules available when setting up conditional formatting on tables. This rule allows you to format cells of a table column based on comparisons with values in another column â you can use this, for example, to highlight any rows where the values in the â2005 Profitsâ column are less than the values in â2004 Profitsâ column. Again, the fact that Excel knows that there are columns in your table makes it possible to surface very easy UI to quickly set up these sorts of conditions.
Thatâs it for now. In my next table post Iâll go into all the work weâve done around tables, formulas, and referencing.
