Once such dynamic template defined, it can be used the same way as a regular static template. A B C A B C define styles for each of the cells going from left to right and then upside down. Number of styles should be a multiple of number of rows so that number of cells in a row equals exactly to number of styles in the template divided by number of rows.ĭefines a template named T which has two rows and three columns (six cells altogether). This command defines a rectangular region of cells. Once all necessary styles are defined, a #template command in the input stream to dynamically define a template out of these styles. When template region is created in the output file, the template processor expects a value to be provided for each template cell associated with a parameter. True - is an optional argument which defines a value placeholder or parameter. The first approach is to declare different styles, represented by cells in the template xls-file supplied with a special and then at runtime define a template useing #template comment has the following - a string defining a name associated with the given style TemplateIt supports two different ways for dynamic template creation. A number of commands is designed to make this possible. Meanwhile in some applications there is a requirement on styles but decision about actual number of cells and more specifically columns needs to be postponed till the runtime. At runtime excel file generation is controlled via limited stream of commands and data. Templates are rectangular regions of Excel's cells which are normally created in advance in excel file. The values will substitute values in the corresponding template cells.įinally there is #end command which tells the processor to stop generating current sheet. Since item template as it was defined, has three parameters, the three values need to be provided with each of these three lines. ![]() They add three times template named item to the end of the current sheet. The next three commands have the same meaning as the second one. This region will be copied from the template workbook to the end of the current sheet. The second line contains name of the header template region. all subsequent commands till #end command are interpreted in the context of the current sheet. PriceList as of 2 becomes current output sheet. The first line tells to the template processor to use sheet PriceList from the template workbook and to create PriceList as of 2 sheet in the output document. This file contains data or better say a stream of commands, driving the template processor to produce the output result. Item is defined in the area A3:C3 and it has three paramaters: iname in A3, price in B3 and date in C3. ![]() The first template named header is defined in the area A2:C2. The bottom right cell of the template should have the following annotation in the cell Workbook defines presentation for the document you are going to generate using templateIt.Ī template workbook may consist of multiple worksheets.īelow is an example of a worksheet with two templates defined.
