如何在AnyGantt中设置月列宽?

是否可以从任何图表更改任何甘特图中月份列的宽度?

This how my table look like

anychart.onDocumentReady(function() {
      // create data tree on our data
      var treeData = anychart.data.tree(getData(), anychart.enums.TreeFillingMethod.AS_TABLE);

      // create resource gantt chart
      chart = anychart.ganttResource();

      // set container id for the chart
      chart.container("container");

      // set data for the chart
      chart.data(treeData);

      // set start splitter position settings
      chart.splitterPosition(200);

      // get chart data grid link to set column settings
      var dataGrid = chart.dataGrid();

      // initiate chart drawing
      chart.draw();
