How to Work with Tabs in the Numbers App for iPad
Tables and charts are built into Keynote and Pages, but Numbers is the main number crunching tool in iWork for iPad. In Numbers, each tab displays a sheet, which can have one or more tables and/or charts on it. Tabs help you organize your Numbers document.
Adding a new tab
As with all the iWork apps, starting a new Numbers document involves choosing a template. Each template has its own pre-defined tabs. (The Blank template has just one tab, cleverly titled Sheet 1.) You can add more tabs by tapping the + tab on the far-right end of the tabs.
Tap the + tab and Numbers asks if you want to add a new sheet or a form. Tap New Sheet, and Numbers creates a new tab for that sheet that contains one table. The sheet is labeled Sheet N where N is the next number in the internal list of sheets you have created.
Deleting or duplicating a tab
If you add a tab by mistake, Numbers allows you to remove it. Also, if you have a tab that you'd like to reuse for a new tab, Numbers allows you to duplicate it. To do either of these actions, tap the tab you want to delete or duplicate, and selection buttons appear above it. All you have to do now is tap the option (Duplicate or Delete) for the action you want to take.
Remember that a double-tap starts editing. A single tap brings up your selection buttons, if they are available for the object you've tapped.
Don't like the order of your tabs? Tap and hold a tab to rearrange the tab order. You simply drag the tab to the right or left in the row of tabs, and then remove your finger when the tab is in the position you want it.
Navigating through tabs
If you have more tabs than can be shown on the screen, just flick right or left to slide along the tabs. Remember to flick in the row of tabs. Flicking on the body of the sheet scrolls over to the right or left of the content on that sheet.
If you're holding your iPad in portrait orientation, turn it to landscape to allow more tabs to fit on the screen.
Changing a tab's name
Double-tapping text anywhere on your iPad allows you to edit it. That goes for tabs, too. Double-tap the name of a tab to begin editing it; you'll also see standard editing commands, such as Select, Select All, and Paste in the selection buttons just above the tab.
