[Description] An array that describes the model of the columns. This is the most important part of the grid. Here I explain only the options used above. For the complete list of options see colModel API name: The name of the column. This name does not have to be the name from the database table, but later we will see how we can use this when we have different data formats. index: The name passed to the server on which to sort the data (note that we could pass column numbers instead). Typically this is the name (or names) from the database – this is server-side sorting, so what you pass depends on what your server expects to receive. width: The width of the column, in pixels. align: The alignment of the column. sortable: Specifies if the data in the grid can be sorted on this column; if false, clicking on the header has no effect.
