Applications of the different sizing modes for columns/rows in a Visual Grid
Relative (default)
The size of the row/column is relative to the other rows/columns.
The default value is a factor of 1. Changing this number to 2 will make the size of the column/row 2x that of other columns/rows in the grid.
Relative sizing is dynamic, meaning if you insert more columns in the grid, all columns with relative sizing enabled will automatically change sizes to fit the new addition, and column B in this example will still be 2x the size of the other columns.
Fixed
Allows you to lock the size at a fixed value.
Independent of other rows/columns and will stay that size no matter how much data you input, or how the dimensions of the whole grid is changed.
This means that if you have a row with a fixed sizing value, that row will stay the same size even if you insert more columns/rows, or resize the grid.
Autofit
Dynamically resizes based on the contents of the columns/rows. This mode has no value, as the size depends on how much text is in the cells of the column.
This mode is good for making your grid robust to changes to textual (or other) data.
