absolute reference的意思|示意

Absolute reference is a type of cell reference used in Microsoft Excel spreadsheets. It's a helpful tool for organizing and managing data. In an absolute reference, an exact cell reference is not changed when copying a formula or a function from one cell to another.

Absolute reference begins with a dollar sign ($). It can be used for both columns and rows. For example, $A$1 is an absolute reference of the cell that is located in the first row and first column of the worksheet. If you copy the formula with an absolute reference to the right or the bottom of the cell, it will stay the same. In contrast, a relative reference is adjusted when you copy a formula from one cell to another.

A single dollar sign ($) makes the row absolute. For example, A$1 means that the row of the cell is absolute whereas the column is relative. That means if you copy the formula into adjacent cells, the relative column will change.

In addition, you can use two dollar signs in a cell reference to make both the row and the column absolute. This way, the same cell reference will not change when you copy the formula.

Absolute reference can also be used in complex formulas that have many arguments. It can be used in some of the arguments to keep them fixed when you copy a formula. For instance, if you use $A$1 in a complex formula, it will always be the same when you copy it to another cell.

Microsoft Excel is a powerful program that has a variety of tools to help make data management easier. Absolute reference is one such tool that can be invaluable for referencing exact cells when organzing data.
