|
||||
When reading a worksheet with the `sheetRows` property set, the ref parameter
|
||||
will use the restricted range. The original range is set at `ws['!fullref']`
|
||||
|
||||
- `sheet['!margins']`: Object representing the page margins. The default values
|
||||
follow Excel's "normal" preset. Excel also has a "wide" and a "narrow" preset
|
||||
but they are stored as raw measurements. The main properties are listed below:
|
||||
|
||||
| key | description | "normal" | "wide" | "narrow" |
|
||||
|----------|------------------------|:---------|:-------|:-------- |
|

|

| `right` | right margin (inches) | `0.7` | `1.0` | `0.25` |
|
||||
| `top` | top margin (inches) | `0.75` | `1.0` | `0.75` |
|
||||
| `bottom` | bottom margin (inches) | `0.75` | `1.0` | `0.75` |
|

| `header` | header margin (inches) | `0.3` | `0.5` | `0.3` |
|
