Prior to the inclusion of tables in HTML, tabular data had to be displayed using the PRE (Preformatted Text) element. The PRE element allows the display of tabular format because all spaces and hard returns included in the text are displayed, rather than ignored. In the example file, columns and rows are created using spaces and hard returns, but these are ignored because they are not contained inside of a PRE element (see Figure 5.1).
To display the spaces and hard returns included in the table, bracket it with a PRE element (see Figure 5.2):
<pre> Alberts $160,251 $245,600 $132,000 $537,851 Brown 225,255 115,995 132,875 474,125 Gilbertson 240,168 390,295 175,000 805,463 Sikorsky 100,678 185,343 260,825 546,846 Yang 265,015 333,838 148,345 747,198 Totals $991,367 $1,271,071 $849,045 $3,111,483 </pre>
Many spreadsheet programs can export data as "print" files (with a .prn file extension) that preserve the spaces between data columns. In Microsoft Excel, for instance, to export your worksheet as a print file, select File, Save As, and specify the file type as Formatted Text (Space delimited) (*.prn). Saving your worksheet as a text file, rather than as a PRN file (or "print" file), eliminates all but one space between the data columns. The PRN file type was originated by Lotus 1-2-3.
