It's important to understand the many ways tables can be manipulated and controlled. Table properties effect the entire table, while Cell Properties effect only individual cells. If you set cell properties the way you want them in the first row of a table, when you add new rows, the same properties will be copied to the new cells. Therefore, it's a good practice to start out with a table of one row by however many columns you need, set the cell properties, then use the tab key to add subsequent rows. Release the mouse button and your table will appear on the page.
Float determines if content outside of the table can wrap around it.
Cell padding and cell spacing determine the amount of space, measured in pixels, between the contents of cells and the border. Increase these values to add a buffer between borders and text or graphics for increased readability. Size settings The size of a table can be controlled either in exact pixel values, or the relative percentage of a browser window. There are advantages to each, depending on the application. In many cases it is desirable to not specify any size, but let the table adjust to the size of the content within it.
