Manipulating Excel Worksheet Rows


by Lisa Macdonald


In Microsoft Excel 2007, row height is measured in points. This is the same unit of measurement used for font size. When printing reports, using points makes it easy to relate the height of rows to the required line spacing. This means that it becomes possible to increase the line spacing by simply increasing the height of your rows.

The familiar techniques used for changing column widths (something that Excel users do far more frequently) can also be used to change row height. Firstly, we can make a selection and, in the Cells section of the Home Tab of the Excel Ribbon, we can choose Format - Row Height. Doubling Excel's default row height will give us a fair approximation of double line spacing. Multiplying the default row height by a factor of 1.5 will give you about 1 1/2 line spacing, and so forth.

Excel's AutoFit facility can also be used to automatically resize the height of rows to accommodate the largest font size contained in a given selection. To AutoFit a single row position the cursor at the bottom of the row heading and simply double-click. To AutoFit a range of rows make a selection and then double-click at the bottom of any of the row headings. The same thing can also be achieved by using Format - AutoFit Row Height in the Cells section of the Home Tab of the Excel Ribbon.

In many circumstances, row height can be completely ignored since Excel will automatically adjust the height of rows to accommodate the largest font size found on each row. For example, let's say we insert a header row at the top of a worksheet centred across all the columns containing data. If we increase the font size of this heading, Excel will automatically increase height of the row to accommodate the new font size, pushing the rest of the data down.

Another technique is to increase the row height interactively. This is done by positioning the cursor on the line below the row heading and dragging up or down. As you drag, Excel displays a tooltip containing the row height in points and in pixels.

When you increase the height of a row, the vertical alignment of your data becomes more apparent. By default, Excel aligns text at the bottom of the cell. When you have increased the row height, as you will often do with headings, changing the vertical alignment to centred is usually more visually appealing.

PC Tablet News: NVIDIA's Quad-Core vs. IPad 2's Dual Core?


by Paul Barber


For a minimum of two generations of chips, NVIDIA has been at the leading edge of making processors for mobile devices, tablets included. In current PC tablet news, Asus head Jonney Shih announced at the AsiaD meeting that their new Transformer Prime will be rolling out in November and that it'll be featuring NVIDIA's new quad-core, Tegra 3. The processor, codenamed Kal-El, is scheduled to run Android tablets with the Ice Cream Sandwich OS.

So what does this all mean for Apple's contender for this generation of tablets, the iPad 2? Well, the iPad 2 runs on Apple A5, a dual core chip. Let's do a quick tablet COMPUTER comparison primarily based on the two processors.

The Apple A5

The A5 has 2 cores and features a CPU clock rate of 800 MHz to 1 GHz, which is a good speed as far as tablet Computers go. It also includes a 512 MB DDR2 RAM at 533 MHz and a GPU clocked at 200 MHz. The A5 was a huge improvement from the A4, doubling the computing speed and upping the graphics power.



The Tegra 3

The Tegra 3, with its four cores (and a fifth companion core), clocks in at 1.5 Ghz. It also features a 12-core GPU, that can output 2560x1600 video. Tablets with this processor can output high-definition video, that's definite. The Asus Transformer Prime is has a mini HDMI port, which pretty much affirms the quad-core's 1080p H.264 High Visibility video decoding. With these specs, the Tegra is reckoned to be 5 times faster than its predecessor, the Tegra 2. Little wonder gadget and PERSONAL COMPUTER tablet news sites are all abuzz about this futuristic chip.



The said NVIDIA quad-core is scheduled to be released later in the year for tablets and early in the new year for smartphones.



We'll certainly see what the Tegra 3 can do in PC tablet news in the future (or at the very least, as soon at the Asus Transformer Prime hits the shelves), but right now, it seems like it's shaping up as a major contender against the Apple iPad 2. Does Apple have something in the works that may have one up the Tegra 3? We'll see, but knowing the electronics giant, it must have something up its sleeve.
