If all tables are linked to the same model, I don’t think you will notice any slowing.

Creating copies of the same table with different columns in different places based on display logic is a nightmare to update later on as you end up having to do the same work over and over again for each table you create in order to make a single minor tweak to all of your many tables.

You can potentially achieve similar results with a single table by dynamically hiding/showing columns, cutting down on the amount of work needed to make broad modifications to the one table in question.

Here’s a function I wrote to dynamically hide/show table columns (tested in V1):

// skuid.custom.setHidden(f)

// takes an object consisting of table and properties and sets item in the table to display or not display based on properties

// options:

// {

//		table: table component to update (optional, use either this or tableId)

//		tableId: id of table component to update (optional, use either this or table)

//		key: the key to use to match table column, can either use the column's label, or fieldId

//		by: "label" or "fieldId" depending on how you want to select the column; defaults to "label"

//		value: true to hide, false to unhide; defaults to true

//		wrapper: optional wrapper to re-render in order to refresh the display so the changes are visible - NOTE: if making more than 1 change at a time do not use this as it will force several re-renders and can slow/freeze the UI

// }

skuid.custom.setHidden = function (f){

	function getKeyBy(object,by,value) {

	    return Object.keys(object).find(key => objectckey]yby] === value);

	}

	let table = f.table;

	if(table===undefined){

		table = skuid.component.getById(f.tableId);

	}

	let key = f.key;

	let set = table._personalizationService.getSettings();

	if (!set.columnSettingsByUID) {

		set.columnSettingsByUID = table.element._columnSettingsByUID;

	}

	let value = f.value;

	if(f.value === undefined){

		value = true;

	}

	let by = f.by;

	if(f.by === undefined){

		by = 'label';

	}



	set.columnSettingsByUIDIgetKeyBy(set.columnSettingsByUID,by,key)].userHidden = value;

	table._personalizationService.updateSettings(set);



	if(f.wrapper !== undefined){

		f.wrapper.render();

	}

}
