# Define Column Width

You can set the width of each column by using width property. If nothing is set to width property, the value of defaultColWidth (property in grid) is used.

You can use %, calc() or auto by setting a string to the width property.

You can also set the minimum and maximum widths by setting the minWidth and maxWidth properties.

<div class="sample1 demo-grid middle"></div>

const records = generatePersons(100);

const grid = new cheetahGrid.ListGrid({
  parentElement: document.querySelector(".sample1"),
  header: [
    {
      field: "check",
      caption: "",
      columnType: "check",
      action: "check",
      minWidth: 50,
      maxWidth: 50,
    },
    {
      field: "personid",
      caption: "ID",
      width: "10%",
      minWidth: "50px",
      maxWidth: "50%",
    },
    { field: "fname", caption: "First Name", width: "auto", minWidth: "120px" },
    { field: "lname", caption: "Last Name", width: "auto", minWidth: "120px" },
    {
      field: "email",
      caption: "Email",
      width: "calc(60% - 110px)",
      minWidth: "120px",
    },
  ],
  defaultColWidth: 50,
});
grid.records = records;
