+- Plugin Hook
+- Optional
+
+`useAbsoluteLayout` is a plugin hook that helps you to form layout of table based on absolute arranegment of cells.
+
+### Table Options
+
+No table options needed
+
+### Column Options
+
+- `width: Number`
+  - `Required`, used to calulate width of the given column header and cell
+- `minWidth: Number`
+  - `Optional`, defaults to 0
+  - Used to set width of the given column if the provided, `width` < `minWidth`
+- `maxWidth: Number`
+  - `Optional`, defaults to Number.MAX_SAFE_INTEGER
+  - Used to limit width of the given column when `width` > `maxWidth`
+
+### Instance Properties
+
+NA
+
+### Row Properties
+ - `getRowProps`
+  - Used to return styles needed to enable absolute layout for rows
+
+### Cell Properties
+ - `getCellProps`
+  - Used to return styles needed to enable absolute layout for rows cells
+
+### Header Properties
+ - `getHeaderProps`
+  - Used to return styles needed to enable absolute layout for headers
