### General Structures
|
|
|
|
|
|
|
|
|
|
Cell address objects are stored as `{c:C, r:R}` where `C` and `R` are 0-indexed
|
|
|
|
|
column and row numbers, respectively. For example, the cell address `B5` is
|
|
|
|
|
represented by the object `{c:1, r:4}`.
|
|
|
|
|
|
|
|
|
|
Cell range objects are stored as `{s:S, e:E}` where `S` is the first cell and
|
|
|
|
|
`E` is the last cell in the range. The ranges are inclusive. For example, the
|
|
|
|
|
range `A3:B7` is represented by the object `{s:{c:0, r:2}, e:{c:1, r:6}}`. Utils
|
|
|
|
|
use the following pattern to walk each of the cells in a range:
|
|
|
|
|
|
|
|
|
|
```js
|
|
|
|
|
for(var R = range.s.r; R <= range.e.r; ++R) {
|
|
|
|
|
for(var C = range.s.c; C <= range.e.c; ++C) {
|
|
|
|
|
var cell_address = {c:C, r:R};
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
```
