This wiki has text formatting rules that will make tables. A table is a span of lines with a | as the first and last character on each line and additional | separating columns. Here is a table. | | 1950 | 1960 | 1970 | | population | 200m | 260m | 340m | | production | 330b | 450b | 920b | Browsers often render empty cells differently as may be seen above. This wiki's text formatting rules interfere with this by combining empty cells with non-empty cells to the left using the ''colspan'' attribute. Here is a typically formatted table with the interpreting fixture identified in the first cell. | Magnitude | | | | | amount | op | total() | print() | | 1000 | + | 1000 | [1000 USD] | | 1000 | + | 2000 | [2000 USD] | | 10000000000 | + | 10000002000 | [10000002000 USD]| | 3000 | - | 9999999000 | [9999999000 USD]| Try this link to see how this looks in wiki formatting codes: http:pages/WikiTables.
