6.23. Choose the Select Column option from the cell menu in the Table Widths Visual Aid. [View full size image] 3. In the Width (W) text box in the Properties Inspector, enter the value 275 and press Enter. The table's column resizes accordingly. 4. To make the table functionally correct, repeat the process for the second column, this time entering a width of 338 in the Width (W) text box in the Properties Inspector. When you're finished, the table is resized proportionally and the Table Widths Visual Aid contains width values for each column. TIP You might be thinking that 640 pixels (the width of the table) minus 275 pixels (the width of the first column) doesn't equal 338 pixels, but instead 365. When sizing columns, it's important to take cell spacing and cell padding into consideration. If you have cell padding and cell spacing, those values must also be deducted from the total size of the table.   If you need to clear the widths for a column, you can do one of two things. First, you can select the entire column (which also selects every cell in that column) and physically remove the numeric pixel value from the Width (W) text box in the Properties Inspector. Second, you can easily remove the width of a column by accessing the column-based menu from the Table Widths Visual Aid and choosing the Clear Column Width option. Of course, cell heights can also be modified. There are two reasons mdoifying cell heights has not been covered in more detail. First, it's just as simple to modify the height as it is to modify the width. When you've learned how to modify the width, modifying the height on your own should be easy. Second, it's not important that you set a cell height. Generally, you'll allow the contents within the cell to adjust the height automatically. Splitting and Merging Cells After you've inserted a table onto the page, more often than not, you might have to merge cells to create more space in the table. For instance, although you might have to work with two independent cells in a row, you might have a bigger image that needs more space than what has been allotted for the columns. Instead of creating a whole new table, you can simply merge cells in an existing row into fewer cells, essentially freeing up the needed space. To merge two or more cells in a table, highlight by clicking, holding, and dragging the cells you want to merge. With the cells highlighted, merge the cells by choosing the Merge Cells icon in the Properties Inspector, by selecting the Merge Cells option from the Table submenu in the context menu, or by choosing the Merge Cells option from the Modify, Table submenu. Any method you choose merges the cells. With the cells now merged, add the subheader_about.gif image (if it hasn't been added already) to the cell. Repeat the process for the last two rows, adding the image subheader_companyevents.gif to the third cell. The result of the merger and image addition will resemble Figure 6.24. Figure 6.24. Merge two or more cells into a a single cell by highlighting the cells to merge and clicking the Merge Cells icon in the Properties Inspector. [View full size image]   Aside from simply merging cells, you can also split bigger cells into smaller cells. For instance, I can place my cursor within a recently merged cell and click the Split Cells icon in the Properties Inspector. Doing this opens the Split Cells dialog box (see Figure 6.25). Figure 6.25. The Split Cells dialog allows you to split cells into smaller individual cells.
